'Wizard' was inspired by the 1975 Hollywood movie 'Tommy' and included likenesses of Roger Daltrey and Ann-Margret on the backglass. This was the last Bally EM game to have its knocker located in the lower cabinet. It was moved to the backbox in subsequent EM games. The Double Bonus playfield insert shown in the flyer is the color green, while actual playfields shown in this listing and elsewhere can have this insert as either green or blue. The reason for the two different colors is unknown to us. Wizard was the first pinball machine to use flip flags. Patent 4,037,842 [TARGET DEVICE FOR PINBALL GAMES] filed May 8, 1975. Granted July 26, 1977 to Jeffrey D. Breslow. Assignee is Marvin Glass & Associates, Chicago, Illinois.
