The style and design are really sweet! I don't think the artist will be able to print and sell them though. Disney lawyers would pounce on them faster than Buzz could say "To infinity and ...." It looks like the designer, Chris Anderson, created them for a portfolio piece while he was in a University. He can definitely use them to garner attention in places like Under Construction and magazines like PRINT and HOW. They should be able to easily land him a nice design job out of college!
