When Tom Forsythe appropriated Barbie dolls for his photography project "Food Chain Barbie", Mattel lost its claims of copyright and trademark infringement against him because his work effectively parodies Barbie and the values she represents.[3] But when Jeff Koons tried to justify his appropriation of Art Rogers' photograph "Puppies" in his sculpture "String of Puppies" with the same parody defense, he lost because his work was not presented as a parody of Rogers' photograph in particular, but of society at large, which was deemed insufficiently justificatory.[4]
