Lansdale, Joe R. Zeppelins West
Summary: A "weird world" tale involving a mix of historical people such as Buffalo Bill with fictional characters such as Frankenstein's monster. But except for a few sentences mentioning that Japan discovered the west coast of North America at the same time as Columbus crossed the Atlantic and that samurai fought at the Little Big Horn, there is no real allohistorical development.
