Andy Warhol's Marilyn Diptych obviously displays the element of repetition, also it can represent symmetry. Although none of the pictures of Marilyn are exactly the same as one another they still trick they eye into thinking that they are the same image. This is one of Warhol's most famous works and is replicated in numerous places. I really like this piece because of the meaning behind it, and that it was produced a couple weeks after Marilyn Monroe's suicide. That factor alone makes the piece quite controversial.
