Some time ago, I inherited a stack of magic from an older magician who was clearing out his basement. One of the items was a miniature grandmother's-necklace-based rope penetration.
It is a 3-sided cabinet. All three pieces are about 8-inches tall. The side pieces are about 18 inches long and they connect to the back piece which is about 20 inches long with a few wingnuts. The sides have two holes drilled side-by-side near the middle. A couple of ropes are apparently tied around a young lady and then threaded through the holes; she magically steps forward, penetrating the ropes.
The pieces are plywood, painted red and yellow.
Abbott's shows a mini-illusion called "MLady Steps Forward" which is similar, but not the same.
Any ideas on the identity of this piece?
