Appropriation in an art sense is deliberately re-inventing somebodies work to make it your own. For example an photographer looked at Vermeers piece ‘woman in blue reading a letter’ and did a modern appropriation of his piece. But during the lecture we also looked at constructivism. Rauschenberg did a two piece series called factum 1 and factum 2. factum 2 is actually just an exact copy of the original. in these works there is also a lot of reference to doubles, and this became a common theme to his practice.
