The Card Puzzle is a self-working prediction routine from the ingenious mind of Woody Aragón. A packet of cards is shown made up of quarters of various jumbo cards. The quarters are shuffled and laid out on the table. The spectator selects four of them under the fairest of conditions. Amazingly all four pieces are part of one single card. A second surprise comes when it is seen that this puzzle card matches a card the spectator selected just moments earlier.
