Translucent playing cards, when held up to the light, reveal a secret image depicting amorous sensuality printed on the middle layer of the pasteboard. These cards became popular in mid-19th century France. It can be noted that the postures of the court cards, superficially presented in classical poses, allow for hidden imagery to be incorporated, sometimes involving nuns. In this example, only the numeral cards contain hidden images as the court cards are not translucent. The hidden images vary from romantic to mildly erotic to pornographic.
In Greek and Roman times eroticism was more freely expressed. India gave us the Kama Sutra. But then it underwent restraint or repression through the middle ages and puritanical times. Erotic playing cards reappeared during the XIX century and translucent cards around the middle of the century. In some examples from this genre, the hidden imagery in the translucent playing card can be more sensual or lewd, as in the example below. The illustrations have nothing to do with the value of the card in the game.
