Comments: Description from Abbott's website: "A card chosen from a borrowed, shuffled deck appears at any number thought of. While shuffling the cards the backs of the cards disappear and then reappear. Next, any card thought of vanishes from the deck-in fact all the faces of all the cards are shown to be blank! But the deck is not ruined-with a wave of his hand the deck is restored to its original condition and returned to its owner."
