Dave Trampier

From 1d4chan

David A Trampier was a comic and game artist. Most famous for Wormy in the pages of Dragon but he'd done a lot of cartoony stuff before that, like for the Drow Trilogy and (more so) S1: Tomb of Horrors.

Trampier did a Sargent (or a Willingham) and disappeared mid-career. He was later spotted driving cabs in the American Midwest.
