We've always wondered who first got the idea to put naughty pictures on playing cards, though odds are it must have been the brainchild of some devious (yet very disciplined) gambler looking to distract his opponents during a high-stakes game of poker. Whatever their origin, you don't seem to find porno playing cards much anymore, which is why you should take the opportunity to enjoy these vintage packs as much as possible. Blography points us to some photos of a vintage set featuring some truly gorgeous nudie pinups—and if you're still feeling nostalgic, there's a collector offering more hardcore versions for sale. Just don't try hiding these up your sleeve at a casino. Even the most clueless dealer will probably notice the difference.
