A card is chosen by a spectator, signed and then returned to the deck.
The magician shuffles the cards then takes a Tic-Tac box out of his pocket.
The spectator's signed card appears instantly, folded in four inside!

Very easy to do !
Ultra visual !
No duplicate !
Everything is examinable !

PS : the box can be shown at 180 degrees if you wish !
