The magician takes four cards from a deck. He shows them and underlines how the Queen is the highest card. He then makes a magical gesture and throws the cards down on the table where they VISIBLY all change into Queens!
A spectator selects and signs a card. WHAM! It's no longer in the deck! Open up the Altoids box, and show them the folded card inside. The spectator sees you remove and hand them the card to reopen - it's their signed card !
