Comedy card spelling trick

The magician shows twelve cards and explains to an audience member who is helping that it is possible to find cards by spelling their names. For example, to find an ace, for ‘A’, place the top card on the bottom of the stack. Then do the same for ‘C’ and ‘E’. Remove the next card and show that it is an ace. The magician repeats this to spell the TWO and the THREE and then the helper tries. Each time the helper tries, a joker is turned up. The magician never gets it wrong. The trick was put out by Davenports, as can be seen from the Davenport demons on the jokers. The full working, and opportunities for comedy, are explained in the Davenport instructions.
