The effect described in this neatly presented and
well designed booklet is based on and inspired by a Basil Horwitz
routine entitled Challenge Duplication ESP. It adds a lot to the
original effect and the full routine is described in details and
purchase of the original Basil Horwitz book in which the routine
appeared is not necessary.
Steve loved the original effect but found that there
were certain elements of the effect that he felt could be improved. The
effect was good to start with but now with the Steve Cook handling and
additions it is near brilliant.
Large format A4 comb-bound book.
