Raoul Hausmann's Mechanical Head (1920) was created during the Berlin Dada movement as a reaction against bourgeois German society and earlier 20th century avant-garde movements like Expressionism, Cubism, and Futurism. The work incorporates everyday objects like a tape measure, ruler, wallet, and watch to dismantle notions of art and commodity. Photomontage also emerged during this period as Dadaists sought to deconstruct images and consumer culture through collage.
