It is mounted on a newer plywood backing with a modern wood material framing. The sign and its total thickness today with the mounting board and frame is 1.
That one appears newer, and albeit it in better condition, it too was a rare offering however my sign may pre-date its manufacture. The sign has a patina to say the least but it is real, historic and authentic.Please feel free to ask any questions you may have.
