This newsreel footage of the Fleischer Studio c.1938 - '39 is relatively rare. It's appeared on a few internet sites before and is on the new Popeye DVD , but this is the first time I've seen it pop up on YouTube.
Even though the process is somewhat simplified for the mass-audience for whom it was intended in this newsreel, there is still some fascinating behind-the-scenes stuff in this look at the making-of a cartoon in the "Golden Age".
The process shown is simplified but accurate.
