Beltrachhi is on probation after spending three years in prision for forging fourteen pieces including works by Max Ernst and Heinrich Campendonk. He was sentenced to six years for his offences.

This is not the first time Beltracchi has claimed he has seen his works on the museum's walls. Last year on Austrain television he alluded to another of his forgeries being in the Albertina, which was suspected to be Max Pechstein's Lying Female Act with Cat, 1909, part of the expressionist expert Hermann Gerlinger's collection which was on show at the museum in 2007.

Director of the Albertina Museum Salzburger Nachrichten commented: "I will make contact and ask if it is the painting from the Gerlinger collection or a different artwork," he said. "Of course we want to know. I said at the beginning that the prosecution made a grave mistake not to use the case to discover all of the fakes."
