This is a very modern studio menu from 1975. It is different from all the other menus I've seen so far in that it has a center opening; very unusual. The art on the menu is of Mickey and Minnie in their pie-eyed personas as was very popular in the 1970s. Just check out that typeface on the cover too!
This is by far the most recent menu I have ever seen from the studio, and the only one to bear an actual date - April 1975.
