This is a new reproduction marquee made of glossy 5 mil flexible polycarbonate material. The 5 mil version is about the thickness of 2 pieces of paper and light will pass through it just like it should. Our graphics have a commercial grade adhesive to make sure your graphics stay where you put them. If you would like a marquee without adhesive you can add on the 10 mil upgrade during checkout for only $5. There is no plexiglass included. This is for the graphic with adhesive ONLY. It is currently 23 11/16 x 7 1/2.
