I used to wonder where precisely Walt Disney's first 2719 Hyperion Ave. studio was located, and what it looked like. Since reading about it first in the 1970s in Dave Smith's article in Michael Barrier's great Funnyworld, I spent hours looking at photos, aerial photographs, maps etc, until I found I had a pretty good impression.
Looking through Cecil Munsey's Disneyana, it appears to me that the "funny looking" Mickey with the button eyes is actually an example of the 1930 British-made pose-able Mickey by the Dean's Rag Book company of London.
First, the WHERE. Here is the front of the Gelsons parking lot, with the original plot of the studio indicated in a blueish hue. We see the very small building, the back yard that has a car shed does not even reach the current Gelsons entrance.
