1980 Penthouse subscription ad targeted men with triangular-shaped penises.
(click ad to read copy)
It's part II of the Penthouse vintage magical ad tour (part I featured a wonderfully racy/cheesy living room scene from 1972 that maybe signaled the birth of amateur porn). Here, the Bob Guccione-founded publication, "by far and away the leader in the sophisticated men's magazine market," according to the copy, directly challenged the cocksmanship of its readers. And the coupon's shape also challenged the scissorship of its readers. Also? I'm sure more than a few men tried to fill that space with a liquid that wasn't ink (eww! that's disgusting! [men are pigs, ladies.]). related: new naked-woman German typeface—Playmatica. (thanks to Simon for the image)
