Hi all. I don't know if everybody knows this already and I'm just late to the game or not. The Youtube account DisneyAnimation has uploaded a ton of old Mickey Mouse cartoons.
Plane Crazy - the first Mickey cartoon produced
The Gallopin' Gaucho
Steamboat Willie - First Mickey cartoon with original sound
Anyways I had a lot of fun watching these and spent a good hour working my way through the list. Enjoy
