One of my favorite ghoulish artists....Eric "Unkle" Pigors!
The above prints are available on his website along with tons of other creepy goodies.
Eric's Toxic Toons figures are based on his work, "Let's Play at the Morgue". Your best bet for snagging a set of these is eBay.
He also did 2 Circus Punks (which I am the proud owner of)! Both were limited to 100 pieces each.
