---Walter Benjamin recognized the importance of Dada when he wrote in 'The Work of Art in the Age of Mechanical Reproduction' that when authenticity ceases to be an important part of making art, "the total function of art is reversed. Instead of being based on ritual it begins to be based on another practice, politics." ---Image:http://www.johnvalentino.com/Teaching/Art190/Projects/190Proj2/Dada.html
Raoul Hausmann. The Art Critic 1919-20. Hausmann, a founder member of the Berlin Dada group, developed photomontage as a tool of satire and political protest. The fragment of a German banknote behind the critic’s neck suggests that he is controlled by capitalist forces. The words in the background are part of a poem poster made by Hausmann to be pasted on the walls of Berlin.
