Probably long before any of us on here were around. Back in the 1950's, years before there were "Hippies," there were "Beatniks." Some of the women look kind of hot. Looks like fun.
You learn something everyday. I never realized sex existed before 1979...
(Yes, I'm joking. Thinking of throwing a "Beatnik Party" sometime especially if the girl in the striped top, miniskirt, and stockings will be my date. Maybe Dove Cameron will wear that for me?
