Easy build Illusion by Paul Osborne.
You really have to see this one to believe it. The magician locks his assistant in a tall, upright restraint. The neck stocks are fastened, the four leather straps and, finally, the ankle stocks. All can be examined as the performer proudly displays his helpless helper. A full length curtain is pulled around the entire unit, momentarily hiding her from view. But wait, somehow we now see her pulling the curtain and Mr. Magician is all locked up.
THE EXCHANGE TAKES LESS THAN FIVE SECONDS! Our plan is a real collector's item, drawn in giant inch and a half scale with all the details included. The prop itself, if staged properly, can be done surrounded. It's easy to build and it makes a great closer to any magic act.
