Silly Symphony
Silly Symphonies is a series of animated short subjects, 75 in total, produced by Walt Disney Productions from 1929 to 1939, while the studio was still located at Hyperion Avenue in the Silver Lake district of Los Angeles. Unlike the Mickey Mouse series, to which it is a sister series, Silly Symphonies did not usually feature continuing characters. Donald Duck got his start in a Silly Symphonies cartoon (The Wise Little Hen, 1934), and Pluto's first appearance without Mickey Mouse was also in a Silly Symphonies cartoon (Just Dogs, 1932).
