Yes, a card from Namibia! This was among the box of “free cards” I was fortunate enough to pick up a while ago. The back says, “Beautiful scenes of NAMIBIA: many a ship stranded at NAMIBIA’S inhospitable coast. Thousands of seals inhabit the shores of the Namib.” Photo and published by H.W. Theiss, Windhoek, Namibia.
From Wiki, I learned that Namibia was under South African control until 1990, when it gained independence. It is located to above and to the northwest of South Africa on a map, with its coast along the Atlantic Ocean.
