A British man who purchased what he thought to be an authentic Marc Chagall painting in 1992 for 100,000 pounds may have to watch it burned to pieces, now that it has been deemed a fake.

According to an article in The Guardian, the Chagall Committee in Paris, headed by the Russian-French modern artist's two granddaughters is determined to destroy the work, entitled "Nude 1909-10." It is the "only authority with the power to declare conclusively whether a work said to be by Chagall is genuine or a forgery,"

The inauthenticity of the painting came to light when Martin Lang, the owner of the painting, decided to submit the artwork to a BBC program called "Fake or Fortune?" which found that some of the color pigments were only developed in the 1930's, after the painting was created.

When Lang handed his painting in for examination, Lang signed a contract stipulating that "March Chagall's heirs could demand the seizure of the work, and/or any other measures stipulated by law." A French law calls for the destruction of fake paintings in front of a magistrate, and a proposal to mark it on the back as fake has been rejected.

Land said he has no plans to seek a refund for his original purchase.
