Traveler and photographer Allan Hailstone visited six cities and four countries on a 1970 trip from London to Africa. He traveled back to Cape Town via Cairo, Nairobi, Pretoria, Johannesburg, and Salisbury in Rhodesia (now Zimbabwe).
South Africa existed under apartheid. I found the people intelligent and cultured. I remember that it was commonplace in Cape Town to see men playing chess in the street. The hotel where I stayed gives an example of the very cheap pricing. It was a luxury hotel, and I had a suite of rooms at £5 per night, which even then was ridiculously cheap. It had a closed-circuit TV in the lobby, which attracted much interest as ordinary TV did not exist.
Here are some fascinating images of Africa from 1970 by Allan Hailstone.
