Here is a postcard titled “Mad Tea Party”. You can see the Matterhorn Bobsleds in the background as well as the now extinct “Skyway”.
According to wikipedia, Mad Tea Party is a spinning tea cup ride at five of the six Disneyland-style theme parks around the world. The ride theme is inspired by the Unbirthday Party scene in Walt Disney’s Alice In Wonderland.
This is a standard size postcard measuring 3 1/2″ X 5 1/2″
Here is a Youtube video of the attraction.
