Douglas Dexter, the brilliant amateur magician, invented this in the early 1900's. A terrific method and presentation that can be done with any cards, even on stage.

Up to three cards are chosen and lost in the deck, they are then are found NOT by the magician but by the spectators, all they have to do is say...STOP! And it'll be on their card - guaranteed. A great way of turning the audience into the stars.
