One of the dorky things I know: Steamboat Willy was not Mickey Mouse's first cartoon. It was only the first one to be released. There were two silent MIckey cartoons produced before it. Including "Plane Crazy," which this image is taken from.
R Giger "Birth Machine." Giger is a Swiss surrealist painter, sculptor and designer best known for his award wining work on the Alien films. I bought this poster when I was 14 and still have it hanging in my bedroom.
