Poet, photographer, and longtime Andy Warhol associate Gerard Malanga is suing artist John Chamberlain over the sale of a silk-screen work attributed to Warhol. The 1967 315 Johns is an enormous grid of Chamberlain's likenesses, and Chamberlain sold the work in 2000 for more than $3 million after the Andy Warhol Art Authentication Board said the piece was genuine. While Chamberlain claims that Warhol gave him the piece in exchange for some of his own, Malanga contends that he and two friends made the work in 1971 as an homage to Warhol. Neither Malanga nor Chamberlain has official documentation for the work.
