Not that this "Shortcuts" feature is any doctorial thesis, it's still of some interest. I recognize a Motorola TV near the top center-right, a Panasonic looking flying saucer TV from the 60's, an RCA looking portable down at the lower left, and the table model dead center looks like one I've seen but can't remember who made it, but the others look made up.
The Predicta-ish set on the left, for example. And was the floor model under the Motorola an actual set made? It looks like something that would have been made in the late 40's.
