Magic Trick: http://www.nexusmagicstore.com/signed-sealed-jardonnet.html
A card is freely selected from the deck, and the spectator signs the card. A second spectator holds a brand new deck, still in its original shrink wrapped cellophane. The signed card vanishes from the deck, and appears Signed and sealed inside the deck, and can be opened by the spectator. To the spectator that's a real Magic Trick.
This trick fooled Penn & Teller.
