This license plate is from the Panama Canal Zone. It is number T-103 for the year 1968. This license plate is in good condition. The reverse side is in very good condition. The front face has many light oxidation spots throughout. This plate was used on a vehicle that put a boat into salt water. I have owned this plate for decades and I have stored it in a dry location. I made no attempt to clean this plate. The oxidation has not increased since I put it in storage. It is still a very good looking plate that would display well on your vehicle or mounted on the wall. A rare plate from this former USA possession.
