Tivoli Box (Simplex Card to Box)
Here's just one of the many effects possible with Arthur Tivoli's Simplex Card to Box:
The magician displays a small, empty cardboard box to the audience (which may be examined) and places it aside on the table. A card is freely selected and signed by a spectator, then replaced in the deck. After a magical gesture, the magician spreads the cards face-up, revealing that the card has disappeared!
The spectator may then open the box which has been resting on the table, removes their signed, folded card and may examine everything!
Includes box and detailed, photo-illustrated instructions."
