The performer shows a miniature coffin and an elegant veneer wood box
that has four numbered "Keyholes" in gold inlay on its lid.

While the performer's back is turned, the spectator is asked to open
the box and place the miniature coffin into any one of the
four compartments inside and then to close the lid.

The performer now makes a "psychic examination" of the box and is instantly able  to
reveal below which numbered "Keyhole" the coffin has been placed.

The effect can immediately be repeated and
everything can be examined.  Electronically-operated detection system is used.

This is a limited edition item and only
35 were available worldwide.
