Dumbo, the Flying Elephant

Dumbo the Flying Elephant is a 1939 children's story by Helen Aberson-Mayer and Harold Pearl. The story was adapted into Dumbo by Walt Disney Productions in 1941. The husband and wife writing duo, Aberson-Mayer and Harold Pearl, co-wrote the Dumbo story and sold it to Roll-a-Book in 1939. No copies of the roll-a-book version have been found, though proofs of the story and examples of earlier versions of the medium indicate it may have existed.
