Prostitute trading card game
Someone has created "a simple and cheap pub game" called Prostitute Trading Trumps, sort of like Magic: The Gathering played with prostitutes' callbox cards. "Getting into Magic requires spending several quid on a starter pack, then several more quid in the vain hope of getting any decent cards in a booster pack. Building a starter pack of Prostitute Trading Trumps involves going into a few phone boxes in the West End of London. Each cards you collect is guaranteed to be a rare limited edition, perhaps available for only a few days." This site includes its own starter pack with 24 sample cards.
