Effect: An envelope is introduced, sealed, and then signed on both the front and back by a spectator. It is now either placed in your pocket or left in full view upon the table. A free choice of a playing card is now allowed. Once this card is committed to memory and signed, it is returned face-up to the face-down deck. The spectator himself pushes his card flush into the deck. The cards are immediately counted to the table. There are only 51, and the face-up selection did not show in the count. Obviously, one card has vanished. The envelope is either removed from the pocket or picked up from the table. The security signatures are confirmed. The envelope is now slowly opened with empty hands and the signed card withdrawn from within. Please note that the selection is really in the envelope and that no palming is required.
