This license plate is from the Panama Canal Zone. It is number 4023 for the year 1958. This plate is in very good condition. The front has light mounting marks and a couple of minor paint marks off of the numbers as shown in the photo. The reverse side has some writing on it as shown in the photo. It would still display well on your vehicle or mounted on the wall. I made no attempt to clean this plate. A rare plate from this former USA possession.
