I suspect we can go a long time before needing separate stamp and cancel threads for Zululand, so I propose we keep them in one thread. Zululand was an independent kingdom prior to becoming a Crown Colony in May 1887. Zululand was annexed to Natal at the end of 1897, and Gibbons tops out at 29 main numbers across two main overprint types and two main key plate designs, plus one postal fiscal.
Here is a nicely-socked cancel for Entonjaneni on Zululand 2, with the first, sans serif, overprint.
The first overprint was done by De La Rue, and the overprint should be 16mm long and 2.75mm tall.

Looks like photobucket's random extension to the file name was censored by the forum software, which replaced some letters with "censored." I reuploaded the image to pb, which should generate a new random filename?
