In the latter part of the 19th and early part of the 20th century, a number of countries maintained post offices in foreign countries, arranged by treaty. Most such offices were operated by European powers in the Middle and Far East. They were partly motivated by the desire to provide reliable postal service for merchants and other foreign nationals in major cities, and partly by suspicion of the local postal service. The currency in use could be either the local currency, or that of the home country.
Additionally, it became the practice of occupying military powers to establish postal services in the occupied country.
An overprint is an additional layer of text or graphics added to the face of a postage or revenue stamp, postal stationery, banknote or ticket after it has been printed. Post offices most often use overprints for internal administrative purposes such as accounting but they are also employed in public mail. Well-recognized varieties include commemorative overprints which are produced for their public appeal and command significant interest in the field of philately.
