TOPIT and TOPIT HANDBOOK

This includes the device (never installed or used; black) and the booklet by Patrick Page.
Bought from Davenport's in London, this booklet describes how to vanish a glass of whisky,
deck of cards, billiard ball; to exchange one object for another; and to produce props seemingly from thin air.
You can read more about it on Wikipedia, but caveat lector.
