Vintage Louis Tannen Add-A-No Magic Prop Effect Illusion Routine 1001 Tricks

Description

A vintage and hard to find effect from Louis Tannen Inc.  Add-A-No - The prop of a thousand and one tricks.
"This is not just one trick but a prop that will do hundreds of effects for you.  For example, it will duplicate every single slate effect ever invented and do it better!  Not just a mental effect, but a fabulous gimmick that will do effects for all types of audiences, even kiddie shows.  Small enough for the pocket and yet large enough for the stage."
Effect:  "An envelope is introduced and placed in full view of the audience.  Three, four or five members of the audience are asked to give you numbers consisting of as many digits as they wish.  These numbers are written on a pad as each spectator gives it to you.  Each spectator watches as you write his number of the pad.  You now have a column of figures, which when totaled will be in the thousands.  The pad is handed to another spectator who totals the column of figures.  A total which no one could have foreseen, as not even the numbers had been thought of yet!  The total is announced and anyone is requested to open the envelope which was put on display before anything was done.  Inside is a prediction which matches the spectator's total exactly.  An ingenious, self-contained mechanical marvel that defies detection.  With many other applications possible.
This item came from the estate of a home magician. Comes with complete instructions, and gimmicked Tablet Board.   Please see pictures of board (last picture) - this is a vintage item and the inside metal has discolored with age.  It appears as though it could be repainted.  I did not attempt to clean.   No on ever sees this hidden compartment, if that matters.
If you have any questions or need additional photos, please ask before purchasing.  Since you will be receiving the secret of this illusion I will not accept returns on this item.
Please see our other listings for more magic items, many vintage and hard to find, from this same magician's estate.  We will be listing more items over the coming weeks.
Thanks.
