This is the first Silly Symphonies short ever.
Silly Symphonies is a series of animated shorts, 75 in total, produced by Walt Disney Productions from 1929 to 1939.
Ub Iwerks is the artist who drew all of the characters and handled the animation.
This animation was a remarkable accomplishment for the time period.
Back in 1929 nobody had ever attempted this type of movement in the characters before.
Enjoy...it's a classic.
