PO Belgian Congo
This historic Belgian Congo postcard shows the Post Office at Boma in 1923.

Note the official wearing a tie (even in the Tropical heat) and the uniformed natives (according to our Nelson’s Encyclopaedia, about a decade earlier the colony possessed a native force from 17,000 to 18,000 infantry, under European offices, mostly Belgians).

The local government was centred at Boma under a Governor General.
