A great walk around effect which can be performed at any time.
A small brass box has been on the table or in the spectator's pocket throughout your act.
The spectator is asked to identify her Zodiac sign; we'll assume she says 'Gemini'. The performer then names his, we'll assume it is 'Taurus'.
For the first time, the performer removes the lid on the box. Inside is a silver dollar-size medallion with the 12 signs of the Zodiac emblazoned on it.
"Examine this closely", the performer tells the spectator as he places the medallion in her hand. "Notice that a small gem has been permanently impressed in the medallion." A ruby is, in fact, mounted in the medallion at the performers sign (in this case, Taurus).
"Turn the medallion over", requests the performer.
Spectator does so, and finds another ruby impressed at the Gemini sign! (or what ever sign happens to be hers).
There is no force of any kind; no pre-show work, no confederates, etc. The outcome will ALWAYS match the spectator's sign no matter what it is. Comes complete with beautiful Okito style brass box, medallion, instructions and patter.
