When The Postmark Makes ALL The Difference - GB Used Abroad
The postmark on a stamp usually indicates where the mail originated from, and is typically found on a stamp of the relevant country.When the stamp and the postmark don't originate from the same country, the stamp is known as a "used abroad".
British colonialisation presented a multitude of reasons why stamps were used abroad, including the establishment of British postal agencies in foreign countries by means of a commercial treaty, satisfying the postal needs of colonies with no local stamps yet produced, and carrying military mail during foreign military campaigns.
These stamps are in my collection, and, again, all were found in bulk lots and not purchased for what they are.
This stamp is Great Britain SG94 4d vermilion Plate 12, issued in 1870. It bears a part duplex A25 of Malta. Although Malta issued stamps in 1860, Great Britain was responsible for the external posts until 1884, hence the use of British stamps until that time
