I saw one t-shirt design which is a parody of Sgt. Pepper's Lonely Hearts Club Band. I think that one is my favorite (and not just because it's the only oen I've seen where Lips is included). But there is one character right next to Sam the Eagle who I can't quite tell who it is... I think it might be Gladys, but the color is off (then again, on the same image Lips is colored green). Or maybe it's the feather boa from the opening number from the Twiggy episode. If I were to submit a design, I'd make sure I didn't include anybody I know aren't owned by Disney, but I'd take a chance with including some Jim Henson Hour characters (it seems unclear as to whether Disney owns them. I would expect Disney to, and Disney did include Waldo in the most recent Muppet Vinymation series, but for some reason Boom! couldn't include them in Muppet Snow White).
