A painting by Spanish Surrealist artist Salvador Dali found in a house clearance is expected to fetch up to £30,000 - after being bought for just £150.
It was found in a house in Cambridge and has since been authenticated as an original.
An anonymous art dealer purchased it and the mixed media piece will be up for sale at an auction in October.
Gabrielle Downie, an associate at auctioneers Cheffins, said: "To handle a genuine rediscovery of a work by who is easily one of the most famous artists in the world, and the godfather of Surrealism, is a real honour."
The art dealer who purchased the piece discovered it had previously been offered for sale at Sotheby's in the 1990s, fully attributed to Dali.
