I recently picked up the following stamp :

Before South Africa became South Africa it was split into 4 large areas each with their own stamps. Natal, Transvaal, Orange Free State and Cape of Good Hope. In 1910 these four joined to become the Union of South Africa. Stamps other than the first stamp of the union were not available until 1913 so it was authorised that pre-union stamps be used throughout the union.
We call these interprovincials. Any Pre-Union stamp with a date after 1910 is worth hanging onto but even more interesting are the ones which were used in other provinces rather than the their initial intended use.
The stamp above - Natal, Postmarked December 1911, used in Cala in the Eastern Cape (Cape Colony).
Anyone else have any to show - I will be looking out for these in future to expand my South African collection.
