Here's a postcard that matches this doll. It shows how the people living in South Africa are dressed in their traditional costume.
Text on the back of the postcard: 'Ndebele women and children at the Ndebele village, North of Pretoria, South Africa. Ndbele-vroue en -kinders in Ndebele bantoestat noord van Pretoria, Suid-Afrika'. Postmark 1979.
