It’s the 50th anniversary of the 1964 New York World’s Fair. One of the most popular attractions was Progressland. It was developed by Disney imagineers for General Electric’s pavilion. The funding by General Electric helped advance the science of building animatronics. The Sherman Brothers added the song “There’s a Great Big Beautiful Tomorrow”.
After the fair Progressland was brought back to Disneyland as The Carousel of Progress.
I also have a GIF set of Walt Disney explaining the different scenes. These photos are from Disney Pix.
