A Tenyo masterpiece has been faithfully revived. A small slatted frame is shown to be completely empty. The magician flips a switch, and a playing card suddenly appears inside. Flip the switch back, and the frame is empty again. The card appears once more, but this time the magician lets it slide out: a regular, full-sized, solid playing card.
The trick is completely self-working, yet deceptive enough to baffle even professional magicians. At first, some audience members may think they understand how the card appears and disappears. Then a real card slides out of the frame, leaving the whole audience dumbfounded.
