Game has two different plastic artwork versions for the upper playfield: "futuristic" style" and "stone castle" style. These differing plastics appear around the lock assembly, near the "W.A.R" lanes, as the upper ramp cover, and as the "magna-save ready" sign. Reportedly, the "futuristic" artwork may be the earlier design. Steve Ritchie confirmed his voice (and not Rich Karstens) is the voice of the Black Knight in this game. Stephanie Rogers and Glo Van Vlack are the voices of the Choir of Angels. We asked Steve about an image in this listing showing a sticker affixed to the upper playfield back wall advertising the sale of BK T-shirts. He replies:The sticker is authentic. It was printed and attached to later games on the back panel, but most were removed by owners and operators. The same message is basically presented in the dmd at different times during the attract mode, but someone in marketing said "What if the game is turned off?" and, "It is good to point out the free T-shirt feature to operators and players." The sticker had low intensity adhesive and was easily peeled off without leaving marks.
