In this ebook a detailed explanation of Nate Leipzig's original method of performing the Card Stab will be found.
From the foreword:
In Chapter III in Down's Art of Magic, the editor, John N. Hilliard, describes a similar trick, but it is not credited to Leipzig, and it is vastly more complicated and difficult than his.
In the hands of the Card Master, the effect was really marvelous as all "old timers" who have seen him perform the routine will agree. Consequently, it is with pleasure that we put it on record, and we do so in the hope that it will become popular in all countries of Anglo-Saxon speech.
