1. Chiswick’s silver skillet

Skillet

A mid-17th century unmarked silver skillet.

This mid-17th century unmarked silver skillet is thought to have been converted to a single-handled porringer in America, where it was a popular item during the 18th century. Chiswick Auctions’ silver and objects of vertu sale in west London on October 23 will include the piece, which has passed by descent from a family in New England. Although catalogued as “probably English circa 1650”, the auction house notes that its apparent lack of hallmarks may indicate it is all of American manufacture. The 2in (5.8cm) high piece, scratch engraved to the side with initials ‘I E’ between a fleur de lis, is guided at £300-5002.

2. Christie’s AI portrait

Edmond de Belamy

'Portrait of Edmond de Belamy’, a work created by an algorithm that will be offered at Christie’s with a $7000-10,000 estimate. Image credit: Obvious.

This Portrait of Edmond de Belamy is the first painting created solely by artificial intelligence that will be offered at a major auction. It is one of 11 unique works in a series called ‘La Famille de Belamy’ conceived by the Paris-based AI collective Obvious. The work measures 23.5in (60cm) square and is printed on canvas. Known as a ‘Generative Adversarial Network’ print, Christie’s described it as “not the product of a human mind”.

It was created by an algorithm composed of two parts. The first part (the ‘generator’) was fed a data set of 15,000 portraits from Old Masters to Modern paintings and created new images based on this input. The second part (the ‘discriminator’) reviewed all outputs until it deemed the result imperceptible as to whether it was done from a human hand or not. It will be offered at Christie’s Prints & Multiples auction in New York on October 23-25 with a $7000-10,000 estimate.

'Winning Penants’ is dated to c.1970 and depicts a scene of fluttering flags and boats in a harbour. The signed 22 x 15in (56 x 38cm) work has an old label for London’s Marlborough Gallery and is guided at £3000-5000.

4. Lehr’s Gauguin bronze self-portrait

Gauguin bronze

A Gauguin bronze self-portrait estimated at €30,000 at Lehr in Berlin.

This bronze self-portrait by Paul Gauguin was cast, presumably in an edition of four, after a plaster model that the artist executed in 1894-95, not long after he had returned from his first visit to Tahiti. The plaster model was exhibited in the Paris Salon d’Automne of 1906. Nothing is known, however, about the identity or whereabouts of the foundry responsible for the casts. This bronze relief was first exhibited in a Berlin gallery and a museum in Basel in 1928. It belonged to the famous art dealer Alfred Flechtheim, whose gallery was forced into liquidation by the Nazis. Flechtheim was able to leave Germany and eventually settled in London where he died in 1937. His premises were taken over by Alex Vömel, who sold the bronze portrait to a German collector whose descendants consigned it for sale. The auctioneer brokered an agreement between the consignor and the descendants of Alfred Flechtheim, so that there are no legal hurdles to the sale, which is expected to bring at least €30,000 for the 14 x 14in (36 x 35cm) bronze at the October 27 sale at Lehr in Berlin.
