This book is indeed worthy the name Encyclopedia. Originally compiled by Doctor Wilhelm von Deusen in collaboration with Mr. Glenn G. Gravatt, and later rewritten by Jean Hugard. It has a very interesting introduction by Ted Annemann where he addresses the issue of inventing new tricks and claiming ownership. This book will provide you with more card tricks than you ever wanted. The combined value of its contents, were the tricks to be computed at their original marketed price, was in the thousands of dollars. Now you can have it for a few bucks.
