Maxello Magic

A spectator picks a card and signs it. She also signs the card case. The card goes back into the deck, deck is shuffled and put back into the case. Everything is placed inside a glass. Cover the glass with a handkerchief and when you remove it, the case is gone! The cards are the there, but the case is not. PLUS, the spectator's card is also gone! Signed case with card in Magician's pocket!
