Johannesburg Series 1

The Johannesburg Chromette postcard 4922 has the caption S.J.P.M.L, Chinese Compound.
The initials stand for Simmer & Jack Proprietory Mines Limited. This information is written on the back of a copy of the card that I have. Would be happy to provide scans should it be of interest.

@Runge are you talking about this card?

If so, please feel free to upload the front and back here.
