If I had a shell, I would have the thing absolutely covered in bumper stickers. This fellow's a little more subdued, but he does have a molluskan variant on my all-time favorite.
I think you may have to view this one at full size to get the joke--not sure if his statement will be visible on the preview.
Mixed media--colored pencil, watercolor, gouache, acrylic ink, fluid acrylic, I forget what all went into this guy. The original is 11 x 14 and will probably go up for auction shortly, e-mail for details. (Prints also available for a mere 10$, again--e-mail!)
