I love cartoon movie posters - and I don't think I've ever seen this particular color Disney-era stock one-sheet before. It looks to be introducing the character to theatre patrons, despite the fact that the white rabbit in the center is not the "lucky rabbit" we know - the real Oswald is running all over the sides. It's also interesting to note Walter Lantz would go with a cuter "white rabbit" design in the later 1930s. Check it out at larger size here.
