This came from an old magician’s estate purchase. No instructions. The items are in good undamaged condition.
The wooden handkerchief stand has a hollow section down its center with a felt top which has a trap flap cut into it. Not sure how the original working went but with a silk handkerchief loaded into the stand you can place the bottomless glass on top of the stand and cover it with a cloth. In that action you could push the silk handkerchief up into the covered glass using one of your fingers. How you proceed from there would be up to you. You could vanish a duplicate silk and have it appear inside the glass, etc.
You receive the wooden stand, real glass bottomless glass, and a U. F. Grant 25 Tricks With A Bottomless Glass instructional sheet.
