Tom Raney in black and white. I have met people who dislike his work, and I quite fervently disagree with them.
Most of, if not all of the pinups were commission pieces, so check either link. He kicks particular ass at using PowerDots, and he likes Kirby stuff. Check out the OMAC and MODOK pinups if you need more proof.
I have met him at several conventions and he is consistently awesome to talk with, so heck the links for his convention schedule too.
