TRANSVAAL: SCARCE NUMERAL-IN-TRIANGLE CANCELLER VARIETY ON COVER. SEE BELOW

THE NUMERAL-IN-TRIANGLE OBLITERATOR

 On 3 May 1889 a large barred triangular obliterator bearing the letters "ZAR" in the corners and a central numeral, ranging from 1 to 90, was brought into use in the Transvaal.

Triangular canceller number "2" was allocated to Potchefstroom, although rarely used, because Potchefstroom believed that, being the first town founded in the Transvaal, it shoould have been allocated number "1", not Pretoria,.

As a sign of protest, the number "2" was inverted when used, as per the cover on offer, posted with inverted number "2" to Germany (12-9-1893) franked 2d and annotated "Bookpost".

A scarce item of Transvaal postal history. As per scan below.
