There is a Picture of Walt Disney hidden in the Carousel of Progress.

It is in the daughter's room in the 1940s on the wall you are facing as you sit in front of the stage wall in the upper left corner.

You should be able to spot four Hidden Mickeys in the final scene.

Mickey appears as a nutcracker on the fireplace mantle, a plush peeking out from a present, a white peppermill on the kitchen counter, and an abstract painting on the dining room wall.

The dog holding the keys in Pirates of the Caribbean and the dog in Carousel of Progress are both patterned after Walt Disney's dog.
