Nyassa Stamps. 1901 issue.
This particular stamp is not especially valuable apart from the geographical, historical and philatelic knowledge you can gain.
Did you know that Nyassa was located in East Africa?
The Nyassa Company was a royal company in the Portuguese colony of Mozambique. This was known as Portuguese East Africa, that had the concession of the lands that include the present provinces of Cabo Delgado and Niassa between 1891 and 1929.
During that time it issued a total of 141 postage stamps, although only a small percentage of these were ever issued for actual postal usage in Nyassa. The rest were created to take advantage of an active philatelic market for the region’s stamps in London.
It was not until 1901 that the Nyassa Company arranged for the printing and release of Nyassa’s own stamps. The stamps were designed by Robert Edgcumbe and printed by Waterlow and Sons in London, and feature 13 stamps of two designs – seven stamps depicting a giraffe browsing a palm tree, and six stamps featuring a pair of dromedaries (not camels!).
The stamps (an example shown here) bear the image of King Carlos I in the upper left hand corner, the value of the stamp in reals, and the name of the colony along the bottom of the stamp.
There you go. Philately, geography and history! With thanks to Wikipedia.
