Bradbury began working for Disney at age 20 and was responsible for key scenes in movies like Bambi, Fantasia, and Pinocchio. After working briefly for Friz Freleng at Warner Bros., he began working for Western Publishing in 1947, illustrating Little Golden Books, other children’s books, and comic books for the Dell Comics and Gold Key Comics imprints along with the Disney Studio Program. Reportedly Walt Disney told Western that they didn’t need his approval for any of Bradbury’s work. Also, Bob Clampett specifically requested Bradbury to illustrate the comic book adaptation of his showTime for Beany. Eye problems forced him to cut back on his output after 1970, though he still continued to work on a few projects for Disney. -Wikipedia
