assembaleged Raoul Hausmann, Mechanical Head, 1920. he made this assemblage look kinda sad in a way.

John Heartfield (not usually considered a Dadaist, per se) He Swallows Gold and Spits Out Tin Plate (1930's). he's showing the evil in hitler. 

                                                                                         Duchamp, The Fountain, 1917. this was just   a regular fountain turned upside down many disagree that it is even art but it is because he's made it his own. i personally think that he's trying to get the point across that we can change things.
