Absolutely charming little first or near first printing of Stuart Robson's classic on the false thumb tip and its use.
Robson [1892] ran a The Conjurer's Shop in New York City and was editor of Conjurer's Chatter. He also invented the Telomatic Deck and innovated many other illusions still in use today. This was his first listed separate publication.

A very good copy, bound in wraps, very solid, with bright and clean pages.
