Thulamela
It is about the ruins of Thulamela on a hilltop in the northeastern corner of the Kruger National ParkBut further information was lacking. Curious, I opened the booklet and found a series of stamps I recognized. It was the series of five strip-style stamps issued on May 8, 1996, for the franking of picture postcards to be transported by airmail. What was striking was that no face value was included on the stamps, but only the indication: Airmail postcard rate.
What relationship did the stamps have with the tabs or attachments below the stamps? The first stamp, with the white rhinoceros, not so much, only that it is found in Kruger National Park.
But buffaloes are also found in that park, as are lions. Did the African woman perhaps have jewelry made of buffalo horn? And was the skeleton that of an African hunter who had died in a lion attack?
The leopard was certainly clear! Probably a king of the realm of Thulamela wearing a leopard skin. And the African elephant? With ivory jewelry?
The text on the inside of the cover did provide a lot of information about the ancient kingdom of Thulamela.
Do you want to know more about Thulamela? Then take a look at www.learn.columbia.edu/thulamelaI myself have also learned a lot from such a simple little notebook.

The provided link to the Thulamela area indicates that only a small part actually lies in South Africa, while the majority is in Zimbabwe. South Africa is releasing beautiful stamps featuring this historical site. And what is Zimbabwe doing?
Hey, that's nice, this publication and the background information about it. It is indeed not immediately clear that it also concerns archaeology, although, after reading the piece, it is.
But what about the face value? Can these stamps simply be put on a postcard?
