A few of my (PG) favorites from a Gilligan's Island-themed art show at The Tonga Hut in LA:
Bob Lizarraga. (From my favorite episode.)
Steven Standoval.
Susannah "Atomikitty" Mosher.
You can see all of the art from the show, as well as purchasing information here (just keep scrolling down). Some of the pieces are NSFW.
*Buy tiki at eBay.
