Here’s a fun Fleischer Studios cartoon that makes great use of the Max Fleischer invention, the Rotograph… it is an early example of the technique, as the cartoon is from 1935 and the patent wasn’t filed until 1936. The Rotograph was a technique of building a miniature set on a turntable that could be rotated while shooting cels in front of it to make it appear that the 2d drawings were in a 3d space.
