This sale is for 1 pair of faces, a frame is available as an option above when ordering. They are discounted because the borders are different on each face, but you can't see the difference when they are mounted in a frame. Like all of our 15" lenses, these feature double strength glass just like the originals, produced using the highest quality glass inks available on the market, and then kiln fired to create a timeless piece of advertising that will last generations! The lenses measure 15" across and will fit all original and reproduction 15" metal bodies. If you need a body, we offer the highest quality die stamped steel bodies available on the market today, please see the bodies tab to add one to your order.
