It seems to be an enclosed part of a beach, what looks like a curved pier like structure.
Found another postcard, same handwriting
On the Rand Simmer & Jack G.M.C.
Braune & Levy, Johannesburg no.1518
It is of an industrial scene and on the back is written.
Here is a picture of the largest battery in the world. there are thirty more stamps in it than any other in the world.
This holds more clues as to the date, it is between 1901 and 1911, going by the name and address of the recepient.
Tried googling but no luck, can anyone suggest what it could be.
Or can anyone more conversant with copyright tell me if I am allowed to put it on here.
Thank you
