“A New York judge ordered that a collector of Andy Warhol artworks be allowed to pursue claims of fraud and unjust enrichment against a foundation that authenticates the artist’s paintings and prints. Joe Simon-Whelan, owner of a Warhol self-portrait, sued the Andy Warhol Foundation for the Visual Arts in federal court in New York in 2007, asking to represent other buyers of the pop artist’s works that were judged to be fakes.”
