Seeburg LS1 front door Art. These are back lit film art that will be placed behind clear glass. Original art will need to be removed or have new glass cut. These are a thick translight material that will fit in the frame behind clear glass. Very similar to newer arcade and pinball backglass. No adhesive required either clean off your old glass or get new flat glass cut same thickness as currently in there. Glass measurements are 18 3/4 x 19 inches, 3/16″ thick.
