A frame housing measuring 4" wide x 5 7/8" high and little over 1/2" thick is shown to have a 1" circular opening at the center. The contents are slid into a spectator's hand and it is found to be a clear plaque with a circular opening to match the frame. Spectators may see inside the frame and a ribbon is handed to the spectator holding the clear plaque.

The spectator is asked to thread the ribbon through the opening in the frame showing the ends hanging down one on each side of the frame. The spectator is asked to drop the plaque into the frame after which both ends of the ribbon are taken and pulled down showing the plaque raises up out of the frame, clear evidence that the plaque is resting on top of the ribbon. The plaque is allowed to fall back into the frame and in only a moment the plaque is pulled out of the frame showing the ribbon has passed through the solid material of the plaque! It is now threaded through the opening all the while with the ends of ribbon being in full view!

A well made piece of apparatus all of plex material. Includes instructions. Condition very fine.
