After selecting a card, the magician shows a little polished aluminum box and takes out a piece of white photographic paper from it. He explains it is a heat-sensitive paper. The spectator puts the chosen card on his right palm, the box with the paper inside over it, and his left hand on top of all. After a few seconds, the spectator opens the box and finds the paper printed with an X-ray image of both his hands and the selected card. Includes the original box and instructions. Very good condition.
