This is Johnny Paul’s routine for this classic comedy card effect.
Effect: Performer has a card selected and returned to the deck. He states he will cause the selected card to vanish from the deck and appear in his inside coat pocket. He reaches in his pocket and partly exposes a card as the Three of Spades. Spectator says that the Three of Spades is not his card. It was the Ten of Spades.
Magician continues to pull the card out (which is eleven inches long) and has ten spots or pips on it and shows it as the Ten of Spades!
Supplied with the special long card and double sided page of instructions.
