Streetside Swindle (EZ-X)

Magician shows an Ace and 3 Blank Face Jumbo Cards (4.4 x 6.6). A blank is removed and put face down on the table. The Ace is placed between the other 2 blank cards. Magically all 3 cards in the Magicians hand turn blank and the card on the table turns into an Ace. This is repeated with slight variations a few times and ends with a stunning climax where the blank cards change to Aces.
