In the instructions it states, "After more than fifty years the card in crystal ball remains one of the most mysterious effects ever seen."  Mike Rogers knew what good close up magic was and he produced this as a workable piece.  The crystal ball is 1" in diameter and manufactured nicely without paste ons and in such a way that when the ball is placed on the red drawstring bag nothing is visible!  A selected card visibly appears in the crystal that the spectator is asked to intently gaze upon.  Includes instructions and very well made.  Condition First Rate.
