From Comics to Toons: Beetle Bailey in Camp Invisible (1964)

 An assignment issued down the chain of command from the Pentagon all the way to dimwitted Private Zero (Howard Morris) leads to chaos when Zero mistakenly uses some top-secret invisible paint to make Camp Swampy disappear.

Here's "Camp Invisible":

Morris would revisit the concept of invisible paint on The Archie Show just four years later. Veteran writer Dennis Marks had one of his first credits as the writer of this farce.
