AJCB:
There are five postcards issued by the Transvaal Post Office for use
by the
Nederlandsche Zuid Afrikaansche Spoorweg Maatschappij (NZASM or ZASM)
(i.e. the Dutch South African Railway Company).
These postcards served as announcement for the arrival of goods,
the cost thereof and as receipt of these goods.
The first issue was in July 1891 (red), the second issue in January
1893 (red),
the third issue in January 1896 (green) and the fourth July 1897
(green).
These four issues were all printed by Joh. Enschede (Holland).
The fifth card (not shown below) was printed in black and
white and produced locally.
Apparently two printings were done, in March 1896 and May 1896.
The text was exactly the same as the other cards although the
letter type (font) was much bolder.
All these cards were known as 'Model No.72'.
