This week's selection from the Vintage Vault comes courtesy the Male Athletic Nudist. While M.A.N. sounds like some sort of comic books villain, it was actually a series of nudist magazines published in the late 1960's. While not having much sexual content, they extol the virtues of sunny & healthy clothes-free lifestyle.
