I don't know the story behind this particular publication.
Al Capp was so far right he'd fall off the edge
The title says it all.
"Creatures from Drop-out space."
It's not her appearance that makes 'Sloppy Belle' unappetizing to Capp, it's the youth culture she represents.
This whole thing ia full of negative assumptions about people because of their appearance.
JOB Corps commissioned Capp to do this pamphlet, I wonder how they felt about the result.
You don't try to promote some service by insulting your intended clients.
Pretty contemptible on Capp's part.
