A “deck” of six cards in a beautifully printed card box, which seems to be the “World’s Thinnest Deck of Cards” because these six cards can be used to locate any card in the deck. The spectator thinks of any card, makes choices among the six cards, and immediately the magician can name the selected cards. This beautiful new version of the famous “number card” effect is especially entertaining and deceptive. Special markings on the backs of the cards allow for a hands-off presentation. Simple to perform and a pleasure to perform.
