It involved only eight drawings and just a few lines of text, and had Red Robin as Dumbo's ally instead of Timothy Mouse . </P> <P> Dumbo was first brought to the attention of Walt Disney in late 1939 by Disney's head of merchandise licensing Kay Kamen, who showed a prototype of the Roll - A-Book that included Dumbo . Disney immediately grasped its possibilities and heartwarming story and purchased the rights to it . </P>
