Backlight film gives the look of original ad glass by mounting it behind the glass. Sandwich the film between two pieces of glass with aluminum tape around the glass or just place the film behind one piece of glass. It lays flat when held in place with aluminum tape around the edges. Viewing from the front is fantastic - just like the blacklight photos and art seen at most airports or original ad glass. You can purchase just the film or have me cut glass and fit the film to the glass for you. These are some that were made for customers. Anything you can think of can be made for you.
