Full length movies of nominees and winner of the Academy Award 1938 for the animated short category as Short Subjects (Cartoons).
Ferdinand the Bull – Walt Disney Productions, RKO Radio – Winner
Brave Little Tailor – Walt Disney Productions, RKO Radio
Mother Goose Goes Hollywood – Walt Disney Productions, RKO Radio
Good Scouts – Walt Disney Productions, RKO Radio
Hunky and Spunky – Fleischer Studios, Paramount
I hope this is the right one, since Hunky and Spunky was a series, but the first one was the one that got the nomination.
