This is a rare gem to find. IF you collect U.F. Grant you either know that or have never seen this prop. You like know it and have never seen it (or at least had the opportunity to purchase one!).
It is a system of getting questions without detection and being able to answer the questions people ask by telepathy.
Joe Stevens put this out a number of years ago as a reproduction but this is the real thing. Comes with the original instructions. It also comes with the original question tickets that were sold with the effect along with customs tickets made up by the magician long ago who performed this (see Photos). It is as complete as you will find.
This was stored in a basement for the last 75 years so it does have a slight musty smell to it (the case more than the prop). I am not going to be sticking my nose into the prop but I know some of you that is important to you (you always ask me about it) so i mention it here.
An incredibly rare prop
