This was a gift given to all attendees of the FISM magic convention in Lausanne, Switzerland in 1991. The novelty is that when a coin is dropped through the slit in the top of the box, it immediately vanishes, although it can still be heard rattling around in the interior which apparently contains no more than a top hat floating in mid-air. This is a well made puzzling illusion. US Patent No. 4967953. Created by Tenyo. Made in Japan.
This is a mysterious novelty. Put a coin in the slot at the top of the money box and watch it vanish before your eyes. The box can be opened only by those who know the secret.
Bought by John Davenport in Japan. When a coin is dropped into the top of the money box, it lands in the internal small box at the bottom and is seen to have mysteriously shrunk.
Made by Tenyo, Japan. Although this is strictly a magic trick, it partly depends on an amazing optical effect, the details of which are not divulged here so as to protect the secret of the trick.
