Postage stamps and postal history of the Niassa Company information

This is a survey of the postage stamps and postal history of the Nyassa Company.

The Nyassa Company, in Portuguese the Companhia do Nyassa, and sometimes spelled "Niassa", was a royal company in the Portuguese colony of Mozambique, then 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,^[1] although only a small percentage of these were ever issued for actual postal usage in Nyassa, the remainder being created to take advantage of a buoyant philatelic market for the region's stamps in London.^[2]
