A very rare find, this 2 1/2 minute non-Disney Ward Kimball short animation film was made in 1968 and was related to the escalation of the Vietnam War. I saw this once back in the 1970s at a special college appearance by Mr. Kimball and never forgot it, but up until now, thanks to YouTube, it has been almost impossible to find and has not been seen much since it was made.
It would probably be rated PG-13, so I'm just including the link, rather than embedding the video. It's more for an adult audience anyway.
