Ah, the torture porn of yesteryear. Behold the cover of Man's Life's 1956 summer issue.
First of all, I want a subscription to this insane magazine. Secondably... I'm intrigued by the issues men were faced with back then: ferocious water-weasels (obviously), tenacious water-sharks (less obvious), persuasively adulterous women and of course "sin-happy vacationists!"
Clearly this was a more primal era, where a man's sensible office job was his only bastion against the swarming hordes of sex-crazed hedonists and furious nature that made up his leisure time.
Fight those urges, man! Squeeze that weasel dry!
