Description

From the Book:
Slydini's Imp-Pass
Slydini kept this one move for himself.
As a general rule, he does not use the move routinely nor has
he taught it to anyone. Once in a very great while, he will use it as a gesture of defiance for the know-it-alls.  However the move isa utili
tarian one and may be used almost anytime during most close-up
routines.
The "Imp-Pass" possesses such subtle and unusual misdirection
that it enabled Slydini to baffle practically all the top-notchers in
magic all over the world. Even though they were alert to his every
move, they still couldn't see anything out-of-the-way, because they
had no idea of what Slydini was doing.
The potential of the "Imp-Pass" opens a completely new vista
in both present and future magic. This additional tool will enable
you to create an endless number of magical originalities
This classic book is an in-depth, step-by-step look into Slydini's greatest methods.  Scores of photos of Slydini at work give you an unprecedented magica how-to.  Want to excel?  Learn from a true master.
