What kind of literature do they mean? Weird porn that you can't buy at the corner gas station, like women with three or more boobs (Still a bad moment in my yoot when my girlfriend and I rummaged through her brother's dresser drawers) Perhaps, some commie propaganda? I'm really not sure what it means. I do know folks don't read signs anyway. I realized this as I read the large 'NO SMOKING' sign that was nailed just above a two foot pile of cigarette butts.
Anyhoo, the music man has a funny song about commies and paranoia.
Also, let's here it for Sheyboygan, home of 'Gus Polinski.'
