What is the name of the very first Mickey Mouse cartoon?

I'm sure Walt would be disappointed with the way greed has taken over Disneyland, Disneyworld, etc. Now the public is paying outrageous prices for these theme parks!

He grew up as an artist an when he was drawing at his office, a real mouse would be in his office. I just seen him on an autobiography movie recently and it was good. I been to disney land back in the 70's an had a blast. He's one to remember for his great disney movies and Mickey of course. 😁
