After the deck is shuffled, twelve cards (one for each month of the year) are shown to the spectator and he thinks of the one corresponding to his birth month.
The twelve cards are isolated in folded papers to prevent any sleight of hand. The spectator names his card and commands it to return to the deck. The folded papers are opened and there are only eleven cards and when shown the thought-of card is not among them. The deck is spread and the thought-of card is found face up back in the deck.
Practically self-working. Easy and fast reset. Can be a different card each time.
