Signature, which was put out by Emerson and West around 1980, was invented and designed by Trevor Lewis, who was always regarded as one of the most practical and smartest people in magic. The props and routine substantiate that repuation. The trick has built in interest and charisma, is very easy to do, and leaves the spectator with a wonderful souvenir, if you so choose.
The item has not been available for a couple decades (at least), but I came across one in a large lot of dealer inventory I purchased. So here is a new and unused example of this wonderful vintage mental magic routine.
EFFECT: Mental magi shows a vinyl note pad, holding a piece of paper, and also a stack of 23 autograph cards that he has collected from celebrities. (The celebs are mostly from the 1970's so I say that this was my father's -- or grandfather's -- autograph collection.) The autograph cards are mixed and set on the table. The spectator is asked to sign her name on notepad paper, and then, using the letters in her own name, she spells it, counting down one autograph card for each letter. When she is done spelling her own name, she has arrived at one of the autograph cards, which is set aside. Let's say it is "Richard Burton". The rest of the autograph cards can be checked -- they are all different. The magician now turns over the paper that the spectator signed and on the other side it says, "Richard Burton".
It is clean and memorable, and the spectator can keep the paper if you wish. (The props include about 12 pre-printed papers, like in the picture, but you can also use any opaque paper, cut to size. Write your own predictions, along with your contact info, and you can give them away without ever worrying about running out!) Also, the celebrity can be different each time you perform -- it is not always the same person.
Something you should know: the trick sometimes ends differently, with a correct prediction being show imprinted on the other side of the notepad. Both possible endings are strong.
Other thing to know: the autograph cards were printed on stock that does not handle well. If they are treated with fanning powder, they handle like a dream. For performance, this is a huge asset. I can powder them for you before shipping if you want -- just let me know when you order. But if you are looking at this item from a "purist-collector's" point-of-view, I can ship them in their original state -- just know that they do not slide freely across each other.
This vintage item from early 1980's is in unused condition, complete with instructions, props and packaging.
