Here is the only airmail label issued in Ciskei.
Ciskei was a Bantustan in the south east of South Africa. It covered an area of 2,970 square miles (7,700 km³), almost entirely surrounded by what was then the Cape Province, and possessed a small coastline along the shore of the Indian Ocean. The name Ciskei means "on this side of the Kei River" (cf. Cisalpine), and is in contrast to the neighboring Bantustan of Transkei.(wikipedia)
