Sign Language by Doug Dyment

… enabling the mystery entertainer both to determine and dramatically reveal a participant’s Zodiac sign, letter by letter, without anything ever having been written or otherwise recorded. It is completely impromptu, can be done at any time, anywhere, and serves as an excellent response to the “read my mind” request that the working mentalist is likely to face from time to time. It also makes for a compelling over-the-telephone demonstration.

Originally popularized by Ray Grismer’s “What’s Your Sign”, this effect has in recent years become a classic of impromptu mentalism. Most versions, however, suffer from less-than-optimal design, with little or no mechanism to keep the performance from looking like a guessing game.This new offering delivers a significantly improved methodological construction, detailed performance instructions (explaining the powerful “ABC” technique), and a carefully crafted script designed to more effectively shroud its modus operandi.

As an added bonus, Sign Language also works with participants who are more advanced in their astrological understanding, and aware of the thirteenth Zodiac sign (Ophiuchus) that is commonly omitted from popular horoscopes.
