Today's #playingcardbacks are from a special #deckofplayingcards used to advertise the pharmaceutical drug Dyrenium in 1964. They're called Diureticards and were created so users can quiz each other on facts about kidney function, diuretics, and Dyrenium while #playingcards 🤣 I would love to use the card backs in one of my modern art creations. DM to commission a piece.
