YouTube user, ‘matbergman’, has taken the time to cut together scenes with the setback process used by the Max Fleischer studio. He has a good description of it and gives us the original name here: The rotograph, patent #2054414, was invented by animator Max Fleischer in 1936. Essentially an enormous, revolving, circular miniature set built in forced perspective, it enabled a fantastic sense of depth and parallax in cartoons produced by the Fleischer Studio in the 1930's.
I’ve included the video and some stills showing Max looking through a camera and setback scene, and a line art diagram that kind of explains the process yet again. These really give a striking effect and I’ve often wonder why they weren’t used on Fleischer’s feature works like Gulliver’s Travels and Mr. Bug Goes to Town?
UPDATE: Here is a great scene form a Popeye cartoon. Watch the cages as they turn showing all sides.
