Item Number: TA6923
You give an imaginary deck to a spectator who shuffles it. Ask him to choose between red and black, then ask him to select a color and finally a value. You remove the deck from its case and you spread the cards; the named card is the only one face-up among a face-down deck!
But there's more. You explain that you were certain of the choice of the card because only this card is printed. The rest of the deck is turned over to show it's blank! Indeed you return the deck face up and all the cards are white! Moreover, the back of the selected card is different!
