Dungeons & Dragons has attracted some unusual individuals over the years, including illustrator David A. Trampier, who just passed away, according to the The Southern Illinoisan:
He disappeared in 1988, leaving his ongoing D&D comic Wormy abruptly unfinished, and retired from illustration to drive a Yellow Taxi in Carbdondale, Illinois. (The above photo from 2003 is one of the only pictures ever snapped of Trampier.)
