Fun and Fancy Free
The film was the artistic predecessor to later Disney films such as "Gulliver Mickey" (1934), "Brave Little Tailor" (1938), and "Fun and Fancy Free" (1947). It also marked the animated debut of Mickey's nephews, although the large number of them is inconsistent with Mickey having only two nephews (Morty and Ferdie Fieldmouse) in the comic strip.
