I recently acquired these Rare Vintage Aviator Playing Cards as a set... They are Stamp Sealed, but with an extremely rare U.S. Playing Card Co. Stamp... It was explained to me (whether true or not, I have yet to verify) that following the taxation on playing cards, and before switching to a sticker style seal, these stamps were used to seal decks... I have never come across this style stamp before and I am offering these for sale or trade in the shop, but still thought that some of you may like to see some pics of these rare and unique decks... Enjoy...
