French Cameo and Tiffany Favrile Glass shine at Grogan’s The June Auction, June 8, 2014

My goal is to publish new posts twice a week — Mondays and Thursdays. However, if you don’t see a new post on Thursday, it’s because I was too busy, so please look for a new one the following Monday.

Grogan and Company held their sale entitled The June Auction on June 8, 2014. Included in the sale were several art glass lots by Daum Nancy, Emile Gallé, and Tiffany Studios. The exceptional results are detailed below.

Tiffany red decorated vase, Grogan lot #496

Tiffany red decorated vase, Grogan lot #496

The better art glass started with lot #496, a red decorated Tiffany Favrile vase. Red is the cat’s meow when it comes to Tiffany and the result did not disappoint. The vase sold for $18,000, against a pre-sale estimate of $2,000 – $3,000.

Daum Nancy Violets bowl, Grogan lot #557

Daum Nancy Violets bowl, Grogan lot #557

The Tiffany vase was followed by lot #557, a huge, 16″ long, Daum Nancy Violets bowl. It more than doubled its high estimate of $4,000, realizing $10,200, including buyer’s premium.

Gallé padded and wheel-carved vase, Grogan lot #615

Gallé padded and wheel-carved vase, Grogan lot #615

Lot #615 was a sophisticated Gallé vase with an applied cabochon, wheel-carved, with internal foil, and a second, tear-like, application. The decoration was undersea with wheel-carved scallop shells. To my eye, the workmanship was outstanding, but the artistry a failure. Luckily for the consignor, the buyer did not ask my opinion. It sold for $15,600, against a pre-sale estimate of $5,000 – $10,000.

Gallé wheel-carved flacon, Grogan lot #620

Gallé wheel-carved flacon, Grogan lot #620

Lot #620 was a gem — an important Gallé perfume bottle, in the original leather case, with a mixed-metal top, made for the Paris Exposition of 1889. This was really a museum-quality object. Estimated to sell for $5,000 – $10,000, it went out the door at $19,200.

James D. Julia, Inc. held their Lamp and Glass auction on June 11th & 12th, 2014. It was a huge two-day sale with 1418 lots crossing the block, and sales of $2.3 million. Some areas showed strength and others weakness, with two private collections performing very well.

Wedgwood Fairyland Lustre Dragon King vase, Julia's lot #1274

Wedgwood Fairyland Lustre Dragon King vase, Julia’s lot #1274

Pair of Moser ewers, Julia's lot #1035

The top lot of the George Klabin collection of Moser glass was #1035, a pair of decorated ewers. Even with a crack to the handle of one of the ewers, the lot almost doubled its high estimate of $10,000, realizing $20,737.50.

Argy-Rousseau Poppy vase, Julia's lot #2000

Argy-Rousseau Poppy vase, Julia’s lot #2000

Tiffany Favrile Lava vase, Julia's lot #2462

Tiffany Favrile Lava vase, Julia’s lot #2462

Lots #2462 and #2560a shared the spotlight for the highest price realized by a Tiffany Favrile vase — $14,220. #2462 was a lovely Lava example, with a hairline crack that was probably original to the making. Lot #2560a was a Paperweight example with white jonquil flowers.

Christie’s New York sells over $5 million at its Important 20th Century Decorative Art & Design sale, June 12, 2014

My goal is to publish new posts twice a week — Mondays and Thursdays. However, if you don’t see a new post on Thursday, it’s because I was too busy, so please look for a new one the following Monday.

Christie’s New York held their Important 20th Century Decorative Art & Design sale on June 12, 2014, a day after Sotheby’s. Christie’s sale was much larger, with 309 lots offered. Of those, 103 did not sell, for a sell-through rate of 67%. The sale totaled $5,954,500, for an average of $28,905 for each lot sold. Sotheby’s sell-through rate was 66%, with an average of $53,290 for each lot sold.

Tiffany Studios Wisteria lamp, Christie's lot #15

Tiffany Studios Wisteria lamp, Christie’s lot #15

Christie’s sale was much less reliant on Tiffany Studios than Sotheby’s. However, the top lot of the Christie’s sale was a Tiffany Studios Wisteria table lamp, lot #15. It sold near the high estimate of $350,000, realizing $437,000, including buyer’s premium. The previous day, Sotheby’s sold a Wisteria lamp of similar quality for $575,000.

Emile-Jacques Ruhlmann cabinet A 'Meuble à Fards, Christie's lot #107

Emile-Jacques Ruhlmann cabinet A ‘Meuble à Fards, Christie’s lot #107

Rare Daum Nancy Penguin vase, Christie's lot #31

Rare Daum Nancy Penguin vase, Christie’s lot #31

The top-selling French cameo glass lot was #31, a rare Daum Nancy Penguin vase. It more than doubled its high estimate of $7,000, to realize $18,750, including buyer’s premium. I would have loved to have bought this vase, but the price realized was the full retail price for a 6¾” example.

Strong results for Tiffany Studios at Sotheby’s New York Important 20th Century Design sale, June 11, 2014

My goal is to publish new posts twice a week — Mondays and Thursdays. However, if you don’t see a new post on Thursday, it’s because I was too busy, so please look for a new one the following Monday.

June is Decorative Arts Month, so the next several blog posts will cover the action at all the major and some of the lesser auction houses. Sotheby’s will be first. Thursday’s post will cover the result of the single-item sale of the world’s rarest stamp, the 1856 British Guiana 1-cent. Christie’s 20th Century results will be posted next Monday, with Bonham’s, Julia’s, Rago’s and others following.

Sotheby’s New York held their Important 20th Century Design sale on June 11, 2014. Included in the sale was an important collection of American art glass, including Tiffany Favrile, from the Estate of Dr. Edward and Helen McConnell. Of the 127 lots offered, 29 were from the McConnell Estate. 100% of the collection sold, with most of the vases easily exceeding their high estimates. Of the remaining 98 lots, only 55 sold, for a sell-through rate of 56% for the non-McConnell items. The sale totaled $4,476,376, for an average of $53,290 for each lot sold.

Important Tiffany Favrile Lava vase, Sotheby's lot #12

Important Tiffany Favrile Lava vase, Sotheby’s lot #12

The top selling lot of the McConnell Estate was no surprise. Lot #12 was a superb example of Tiffany Favrile Lava glass. It soared past its estimate of $75,000 — $100,000, to sell for $197,000, including buyer’s premium.

Tiffany Studios Wisteria table lamp, Sotheby's lot #44

Tiffany Studios Wisteria table lamp, Sotheby’s lot #44

Neither was the top selling Tiffany lamp of the sale a surprise. Lot #44 was a nice example of the Wisteria pattern. It sold within the estimate of $300,000 — $500,000, realizing $575,000.

Paul Lobel silver-plated coffee service, Sotheby's lot #77

Paul Lobel silver-plated coffee service, Sotheby’s lot #77

The second highest price of the sale went to an important Paul Lobel silver-plated coffee service. It realized $377,000, against a pre-sale estimate of $200,000 — $300,000. Considering the set wasn’t even sterling silver, the price was impressive, but again not a surprise.

Lamps sell well at Bonham’s Los Angeles 20th Century Decorative Arts sale, April 16, 2014

My goal is to publish new posts twice a week — Mondays and Thursdays. However, if you don’t see a new post on Thursday, it’s because I was too busy, so please look for a new one the following Monday.

Bonham’s Los Angeles held a diverse 20th Century Decorative Arts sale on April 16, 2014. Included in the sale were a number of lots by Tiffany Studios and The Pairpoint Co. that performed very well.

A Tiffany Studios Moorish chandelier, Bonham's lot #2237

A Tiffany Studios Moorish chandelier, Bonham’s lot #2237

One of the top lots of the sale was #2237, a Tiffany Studios Moorish chandelier. It soared past its pre-sale estimate of $12,000 – $18,000 to sell for $46,250, including buyer’s premium.

A set of Tiffany Favrile tulip shades, Bonham's lot #2246

A set of Tiffany Favrile tulip shades, Bonham’s lot #2246

A matching set of Tiffany Favrile gold tulip shades doubled its high estimate of $4,000 to realize $10,000, including buyer’s premium. What was even more surprising was that only six of the nine shades were in perfect condition. I’m guessing that the buyer of the Moorish chandelier might have been the buyer of these shades, as they’re the same as the chandelier’s.

Rare Pairpoint Geranium puffy table lamp, Bonham's lot #2238

Rare Pairpoint Geranium puffy table lamp, Bonham’s lot #2238

A rare Pairpoint puffy Geranium table lamp in an equally rare potted base sold well above its high estimate of $5,000, to sell for $11,250.

I tried to buy some of the sale’s better items, but prices were too strong, so I bought nothing. For the complete results of the sale, click here.

Prices were nuts at Woody Auction’s The late Dr. Ernest Rieger Collection sale, March 20, 2014

My goal is to publish new posts twice a week — Mondays and Thursdays. However, if you don’t see a new post on Thursday, it’s because I was too busy, so please look for a new one the following Monday.

Woody Auction held a sale, The late Dr. Ernest Rieger Collection, on March 20, 2014, with superb results. Bidding throughout the sale was fiercely competitive, with multiple bidders vying for the “fresh meat”. Dr. Rieger had put together a varied and high quality collection and it was put up at auction with no reserves, or estimates, on any item. They were going to sell for whatever the market would bear, and the great results bore out that modus operandi. I tried to buy many items, but was outbid on most everything. But I’m not complaining, as it means the market is healthy.

Fantastic Tiffany Favrile vase, Woody's lot #383

Fantastic Tiffany Favrile vase, Woody’s lot #383

The best prices were achieved by the high quality offerings of Tiffany Favrile glass, French cameo glass and English cameo glass. Top lot of the sale went to Tiffany, with lot #383, a magnificent, very rare, paperweight vase with several wheel-carved insects. It sold for $60,000.

Rare Daum Nancy Rain table lamp, Woody's lot #161

Rare Daum Nancy Rain table lamp, Woody’s lot #161

The top French cameo glass lot of the sale was a rare Daum Nancy Rain scenic table lamp, 13½” tall. It soared to $38,000.

Superb Webb cameo vase, Woody's lot #150

Superb Webb cameo vase, Woody’s lot #150

A beautifully carved English cameo vase by Webb was the top lot of the English glass offerings. It went out the door at $35,000.

Martin Brothers leads the way at Rago’s 20th Century Decorative Arts Auction, March 1, 2014

My goal is to publish new posts twice a week — Mondays and Thursdays. However, if you don’t see a new post on Thursday, it’s because I was too busy, so please look for a new one the following Monday.

David Rago held two early 20th Century sales yesterday, March 1, 2014, The Lillian C. Hoffman Collection of American and European Ceramics and 20th Century Decorative Arts Auction. The Martin Brothers were well represented in both sales and did not disappoint. Many of the offerings exceeded their high estimates.

A rare Martin Brothers triple bird, Rago lot #18

A rare Martin Brothers triple bird, Rago lot #18

As expected, lot #18, a rare Martin Brothers triple bird, led the way. It easily trounced its estimate of $30,000 – $40,000, to sell for $112,500, including buyer’s premium. Another triple bird, lot #199, smaller, with no wooden stand, and probably an early re-glaze, sold within its pre-sale estimate, realizing $46,875.

Martin Brother frog tobacco jar, Rago lot #17

Martin Brother frog tobacco jar, Rago lot #17

A wonderful Martin Brothers frog jar, lot #17, also did very well. It nearly quadrupled its pre-sale estimate of $15,000 – $20,000, to sell for $87,500.

A rare Tiffany Favrile blue Jack-in-the-Pulpit vase, Rago lot #435

A rare Tiffany Favrile blue Jack-in-the-Pulpit vase, Rago lot #435

The cover lot of the 20th Century sale, a very rare blue Tiffany Favrile Jack-in-the-Pulpit vase, was the best Tiffany Studios item in the sale. To my surprise, it sold for the low estimate of $50,000 + buyer’s premium, for a total of $62,500. I thought it had a good chance of exceeding its high estimate, but some minor factory flaws may have hurt its result.

Sotheby’s New York sells a Tiffany Studios Wisteria table lamp for $1,565,000, December 18, 2013

My goal is to publish new posts twice a week — Mondays and Thursdays. However, if you don’t see a new post on Thursday, it’s because I was too busy, so please look for a new one the following Monday.

December is 20th Century month, with every major and many minor auction houses holding a sale. Sotheby’s held two sales yesterday, December 18, 2013, with some truly impressive individual results. The Important Tiffany auction realized total sales of $3,675,625, while the Important 20th Century Design sale realized $5,145,500.

Tiffany Studios Wisteria table lamp, Sotheby's lot #330

Tiffany Studios Wisteria table lamp, Sotheby’s lot #330

First among the results was a world-record price for a Tiffany Studios Wisteria table lamp at auction. Sold as lot #330, with a pre-sale estimate of $600,000 — 800,000, it soared to $1,565,000, with two phone bidders who wouldn’t give up. The color was strong and the provenance royal, from Baron Heinrich Thyssen-Bornemisza of Spain.

Tiffany Studios Double Poinsettia table lamp. Sotheby's lot #317

Tiffany Studios Double Poinsettia table lamp. Sotheby’s lot #317

Another Tiffany lamp with a super result was lot #317, a 22″ Double Poinsettia. It was a particularly nice example, with strong red and blue colors — just what collectors like. It sold for $221,000, against an estimate of $120,000 — $180,000.

Wonderful, rare Tiffany Favrile red carved vase, Sotheby's lot #304

Wonderful, rare Tiffany Favrile red carved vase, Sotheby’s lot #304

The selection of Tiffany Favrile vases in the sale was limited, but choice. I lusted for lot #304, a fantastic cherry red Tiffany Favrile vase, completely wheel-carved with flowers and leaves. It sold for $21,250, against an estimate of $8,000 — $12,000. Unfortunately, I was the underbidder. There’s only so much a dealer can pay. Retail buyers will win every time.

There were some disappointments too. The cover lot, a rare Tiffany Bat lamp failed to reach its reserve of $500,000, against an estimate of $550,000 – $750,000. Another important lot, a piano from Louis Comfort Tiffany’s studio in the Charles Tiffany mansion in NYC, also failed to sell, against a reserve of $200,000 – $300,000.

We’ll be busy buying for the next several weeks in anticipation of the important Florida shows, starting with the Miami National Antiques Show on January 24, 2014.

It will immediately follow the important Palm Beach Antiques Show.

Two more VERY interesting items from Christie’s Interiors sale, December 11, 2013

My goal is to publish new posts twice a week — Mondays and Thursdays. However, if you don’t see a new post on Thursday, it’s because I was too busy, so please look for a new one the following Monday.

Christie’s held their Interiors sale last week, December 11-12, 2013. I last wrote about a couple of interesting French lots in the sale. Today’s post will be about two very curious American lots from the same sale. They’re both interesting, but for very different reasons. Let me explain.

Christie's lot #254 is on the left.  A complete vase is on the right.

Christie’s lot #254 is on the left. A complete vase is on the right.

Lot #254 was a rare and very desirable Tiffany Favrile vase, but not exactly this example. You see it was only half a Tiffany vase. Someone, sometime, in its history decided to re-carve the vase into an amusing shape. It’s hard to believe this was done at the factory, so the best explanation is that someone took a seriously damaged vase and became very creative. The workmanship involved in cutting the vase was expert. Christie’s didn’t even think it was an authentic Tiffany Favrile vase, so they called it “AN AMERICAN CLEAR AND COLORED CAMEO GLASS VASE, SIGNED IN ETCH ‘L.C. TIFFANY-FAVRILE’, EARLY 20TH CENTURY”. In fact, if it were complete, it was a killer example. The color was much better than usual and the grape clusters were bigger. Even with the creative carving, it realized $3,125, including the buyer’s premium, against a pre-sale estimate of $1,500 – $2,000.

Pairpoint Hummingbird & Roses puffy table lamp, Christie's lot #463

Pairpoint Hummingbird & Roses puffy table lamp, Christie’s lot #463

Lot #463, a Pairpoint Hummingbird & Roses puffy table lamp, wasn’t quite as amusing, but still interesting. Why was the lamp photographed with the shade on the table? Take a look at the spider arms. They’re upside-down, so the shade couldn’t possibly rest on the arms. That tickles me. This was another lot that I had hoped to sneak up on. The shade was the larger of two versions, 16″ in diameter, with no chips and a very desirable green background. BUT, I didn’t bid one penny for it. Upon inspection, the interior paint was peeling off the roses — a very rare occurrence. How disappointing! The lamp failed to sell, even with a very fair estimate of $4,000 – $6,000 and a likely reserve of half the low estimate, or $2,000. The paint peeling was subtle, so it probably wouldn’t have been detected in a condition report. This is one bullet I dodged by viewing the item in person.

We’ll be busy buying for the next several weeks in anticipation of the important Florida shows, starting with the Miami National Antiques Show on January 24, 2014. We’ll end our winter schedule with the wonderful Grove Park Inn Arts & Crafts Conference, February 21 – 23, 2014.

Heritage’s Tiffany, Lalique & Art Glass auction grosses over $1 million, December 4, 2013

My goal is to publish new posts twice a week — Mondays and Thursdays. However, if you don’t see a new post on Thursday, it’s because I was too busy, so please look for a new one the following Monday.

Heritage Auction held a Tiffany, Lalique & Art Glass auction on December 4, 2013. It wasn’t a stellar sale, with mostly B level items, but the results were decent. 344 of the 364 offerings sold, for a high sell-through rate. The sale totaled $1,030,706, for an average of $2,996 per sold item.

Tiffany Studios 22" Belted Turtleback table lamp, Heritage lot #89039

Tiffany Studios 22″ Belted Turtleback table lamp, Heritage lot #89039

Top lot of the sale was a Tiffany Studios 22″ Belted Turtleback table lamp, with a rare base, in a non-mosaic tile version. When inset with mosaic tiles, this same base is much more valuable. The lamp sold just below the low estimate of $100,000, for a total of $118,750, including buyer’s premium. The consignor was lucky to sell the lamp, as it wasn’t exciting and carried an overly optimistic estimate.

Fine Tiffany Favrile paperweight vase, Heritage lot #89049

Fine Tiffany Favrile paperweight vase, Heritage lot #89049

The top Tiffany Favrile glass lot of the auction was #89049, a fine paperweight example, purchased in 1978 from Grover Antiques. It sold just below its low estimate of $25,000, for a final price of $30,000.

Fine Loetz black bottom vase, Heritage lot #89172

Fine Loetz black bottom vase, Heritage lot #89172

The most interesting lot of the sale was #89172, a rare, desirable, signed Loetz 7″ black bottom vase. It carried a ridiculously low estimate of $1,000 – $1,500. Black bottom Loetz vases have been selling in the $10,000 price range for the last 20 years, so why did Heritage put a $1,000 – $1,500 estimate? Only two explanations make sense. First they didn’t know, or second they did it purposely to generate excitement. Regardless of the reason, the vase soared to a final price of $13,750.

We’ll be busy buying for the next couple of months in anticipation of the important Florida shows, starting with the Miami National Antiques Show on January 24, 2014. We’ll end our winter schedule with the wonderful Grove Park Inn Arts & Crafts Conference, February 21 – 23, 2014. We last exhibited there a few years ago and couldn’t do it again because of scheduling conflicts. This year there were no conflicts, so we’re happy to return. It will immediately follow the important Palm Beach Antiques Show.
