I just found out that Robert Rauschenberg died the other day. I wasn't overly familiar with his work, but Andrew and I happened to catch an exhibit of his prints a couple months ago that impressed me. Back in the 50's he erased a drawing by Willem de Kooning, a well known Dutch painter, and called it art. He talks about what he was doing with that piece and why in this interview. Interesting insight into the mind of an artist.
