Raoul Hausmann: The Art Critic (Der Kunstkritiker - 1919-20). See the article by Michael Glover "Great Works: The Art Critic 1919-20 (31.8x25.4 cms)" in The Independent.
Hausmann, a founding member of the Berlin Dada group, developed photomontage as a tool of satire and political protest. Although the 'art critic' is identified by a stamp as George Grosz, another member of the group, the image was probably an anonymous figure cut from a magazine. 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.
