This is a new 2 piece top and bottom 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 graphics with adhesive ONLY. The white box areas of the marquee are NOT cutout. However, the material will allow light to pass through it. The bottom piece is 20 1/8 x 7 1/4. The top piece is 9 7/8 x 4 3/4.
