Unusual (For me)SHIP MAIL SECTION
Author : agondoz
If I remember, another reason for posting this cover concerned the change from "Ship Mail Room" to "Ship Mail Section". From the few covers that I have seen, perhaps the "Ship Mail Section" marking was in use from 1965 to 1966.
Perhaps the use of a "Sea Mail Section" postmark ended in 1966?
