A series of strips from a failed attempt by Walter Lantz (of Woody Woodpecker fame) to create an Oswald the Rabbit strip recently went up on Ebay. You can see scanned in copies over on the Classic Cartoons blog.
Of course, Walt Disney and Ub Iwerks were the original creators of Oswald, though this rabbit bears as much resemblance to those early cartoons an issue of Acme Novelty Library does to World War Hulk.
