When festival poster art attacks!

A coincidence, I'm sure, but an amusing one:

Atlanta IFFB
The 1983 Atlanta
Film Festival poster.
The 2009 Independent
Film Festival Boston art.

Is there a common image source for both? Someone knowledgeable in art history, please let me know.

(Update: some Googling later, it looks like both works are the same take on an illustration in Gray's Anatomy.)
