This is a Painted piece of Flash Glass, made for the Pilot of Air Force One. The whole thing was a window of Air Force One with this as the Seal in the lower corner, And this was just an extra made just in case. And then the window got broke and I had to do repair on it years later, darn.
    The technique was done with a photo-rezist on the back side with the Flash Glass, Sandblasted, and then the painting to get all the Lettering and Red, White, and Blue of our Seal of the United States. It really came out nice.
