A rare and diabolical secret for identifying cards. The masters of this particular subterfuge are few and far between, but their exploits are legendary. Walter Scott, The Phantom at the Card Table, performed this feat for a group of the most knowledgeable men in magic almost 100 years ago, and that performance is still a hot topic of discussion today.
Recently James Riser developed a stunning example of the apparatus generally used to put in the work. It is small, reliable, and will last a lifetime. Additionally no extra tools are required to make adjustments.
In addition to the precision made, expertly crafted apparatus, a small booklet is included detailing some of the history and applications of this amazing secret. It should help you on your way to proficiency and the ability to use this rare tool to your advantage!
