The Silly Symphony banner was used by Walt Disney between 1929 and 1939. The first was The Skelton Dance, notable for its particular blending of movement with sound.
Then, in 1932, Disney harnessed the promise of Technicolor with Flowers and Trees.
Finally, in 1937, Disney was experimenting with the techniques that would make Snow White feel more convincing. In Academy Award winner The Old Mill, we see the first use of the multiplane camera.
