This license plate is from the Panama Canal Zone. It is number 708 for the year 1964. This plate is in very nice condition, but there are a few light scratches and marks indicating that this plate was mounted on a car. The bottom of the reverse side has some discoloration. This might be the result of being mounted and I made no attempt to clean it. It does not look like oxidation. A rare plate from this former USA possession and in very nice overall condition.
