You’ve taken a playing card, placed it in an envelope and left it in full view. The spectator thinks of any hour of the day. You count off 12 cards from a deck and arrange them in the order of a clock dial. Starting at one o’clock, you count up to the spectator’s chosen hour and show that your prediction card exactly matches the card at his selected hour. Not only that, but these are the only two card that have matching backs! Each of all the other cards in the entire deck has a different back design. Includes instructions. Very good condition.
