Ceci N’est Pas Un Warhol?

Careful, this might not be a Warhol. After all, it’s only a signed drawing of a Campbell’s Soup can. But it’s in a Warhol book that has the Warhol self-portrait on the cover which Warhol presented to a collaborator–and which the Warhol Authentication Board declared inauthentic two years ago. So yeah, you never really know.
