Details of full name on Johannesburg Card

@Runge thanks, what is missing from the card?

It looks like this set captures “Johannesburg” on the set title:

I sent these scans because the reverse shows what the initials in caption represent.
S.J.P.M.L. = Simmer Jack Proprietary Mines Limited.
I thought it was interesting and hoped someone else might agree.
Regards Anthony

@Runge oh I didn’t notice, thanks for that, I’ve uploaded the back, and added a comment.
