Wow. Jill Greenberg is an amazing photographer/photomanipulator (she's responsible for some very well known portraits of celebrities like John Stewart, Larry David and Sasha Cohen). But where she really shines? Her Apes and Monkeys series of photo manipulations.
Edit: As V. Blame points out, this is a follow-up post to an earlier post by Lisa pimping Jill's monkey portrait book. It was all intentional!
