Establishes the political and artistic context for Asger Jorn's Modifications, a series of détourned kitsch canvases begun in Cobra around 1950 but first realized on flea market paintings in 1959 with Enrico Baj. Considers the Situationist theorization of the works as a form of détournement in the context of the post war art world's recuperation of the avant-garde; the impact of Dada, Duchamp and Picabia on the series; and the broader context of Nouveau Réalisme and the concurrent but only tangentially related series of Modifications by Daniel Spoerri.
