This logo was designed by Jim Phillips back in the early 80s. It, too, is an image that solidly represents that era of skateboarding. I think people were drawn to it because it was creepy and whimsical at the same time. From the overall shape to the concept and original color scheme, it's brilliant in its simplicity and interesting enough to have been tattooed onto countless thousands of skaters and non-skaters alike.
