réalistes made extensive use of collage and assemblage as well
as painting. They incorporated real objects directly into their work, acknowledging a debt to the readymades of Marcel Duchamp. The leading exponents of this aspect were Arman, César, Christo, Jean Tinguely and Daniel Spoerri.
Raymond Hains, Mimmo Rotella, Jacques Mahé de la Villeglé and Wolf Vostell developed the décollage, or torn poster technique, making striking works from accumulated layers of posters they removed from advertising hoardings.
