All of the art work is great and reminds me of the Shorts with Goofy from the late 40's and 50's. If you noticed the slide with Goofy riding the Rocket? This is why I really do appreciate the imagineers. There is so many levels of detail. I always am taking pictures and finding things that I did not see while at the parks once I get home. On the rocket is the name Dolores. I thought there might be something there and did a quick search and guess what? Dolores is a character in a couple of the Goofy shorts. Dolores the Elephant was first seen in 1945 in the short Tiger Trouble. She makes another appearance in The Big Wash in 1948. In the Big Wash, look for Dolores' water bowl for her name.
So keep your eyes open for the details. You never know what they'll lead you too.
