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.
idk but based on my observation, this is some kind of symbol that most people are just stereotype with money. The barcode indicated that people are easily saying something that are related with money in any general things, but that's only based on my observation though, lol
