A painting of the late French fashion designer Coco Chanel attributed to Andy Warhol has been sold for $247,000 by Stevens Auction Company in Aberdeen, Miss.

The sale occurred Aug. 8 and was confirmed Tuesday by company owner Dwight Stevens, who said the purchaser wished to remain anonymous.

The portrait was acquired by the seller’s grandmother from a Canadian gallery in 1985 and has been in the family collection since. It measures 15 inches by 17½ inches and is said to have an authenticating stamp by the artist’s estate.

Former Andy Warhol Museum director Tom Sokolowski and national critic Blake Gopnik both expressed doubts to artnet News based on an image of the painting.

Mr. Stevens said his firm had several people look at the work pre-auction. “We were relying on others. We brought in art dealers and so-called experts.”

In the end, he said, it’s up to the buyer to determine whether they believe it is a Warhol. Neither The Andy Warhol Museum nor The Andy Warhol Foundation for the Visual Arts would comment on the work’s authenticity.

“The Warhol is not in the business of authenticating nor valuing works of art. That said, our staff will not be weighing in on the topic,” Rick Armstrong, the museum’s communications manager, wrote in an email.

The foundation told artnet News, “We do not offer opinions on works of art purported to be by Andy Warhol, whether on or off the record.”
