I just looked through the book on the art of William Stout, and there's a lot to learn in there. He worked with the best and most famous people you've ever heard of, Henson, Spielberg, Lucas, Disney

the first merch that Lucas had made, was commissioning Stout to do the art for Burger King glasses! 

Lucas also commissioned Stout to do the poster work for the re-release of American Graffiti
