For whatever reason i've been trying to find a sketch. I can't remember who did it, but it's a B&W sketch of a guy sitting on a chair drawing himself, and it's photorealistic, and the guy's hair is all messed up and he has glasses on. The name totally slips my mind.
If anyone could help me jog my memory it'd be much appreciated.
 got it. It's Chuck Close's "Big Self-Portrait" i was thinking of.
