What is this we have here? It's the Marceline Animated Film Company.
Quality Entertainment for You and Your Family
And, as we can see from the windows at either side, the Film Company is run by the Disney Brothers - Roy O. Disney and Walter E. Disney. I hope they could produce the animations that we so desire!
Of course, the name of this window is a throwback to the town in Missouri where Walt, and his family, lived for 4 years during his childhood. Marceline is often referred to as the place which inspired Main Street U.S.A., and - consequently - World Bazaar.
