After allegedly buying Andy Warhol’s 1981 Dollar Sign painting at a New Jersey flea market for $180, Jason Beltrez brought the painting to Christie’s auction house to sell. Christie’s checked with the Art Loss Register and determined the painting had been stolen from Martin Lawrence Galleries in SoHo on February 14, 1998. The battle now begins as the art gallery is suing Mr. Beltrez for ownership.
