"
The White Rhinoceros or Square-lipped rhinoceros (Ceratotherium simum) is one of the five species of rhinoceros that still exist and is one of the few megafaunal species left. It has a wide mouth used for grazing and is the most social of all rhino species. The White Rhino consists of two subspecies: the Southern White Rhino, with an estimated 17,480 wild-living animals at the end of 2007 (IUCN 2008), and the much rarer Northern White Rhino. The northern subspecies may have eight remaining worldwide — all in captivity.[3]"
I like this stamp because it shows not only the rhinos, but it also gives you a clue, a research starting point, a spark for your mind: the map of the region of KwaZulu/Natal, in the context of South Africa.
So, the point is: don't just look at this rhino stamp and move on with your oh, so busy life.
While you are at it, at least take a quick look at the (wikipedia, for example) entry for South Africa.
Expand your horizon. Horizontally. Coz now it may be too much of a vertical horizon, ultra-specialized in your tiny square of knowledge required to do your job, whatever that is.

Happy Sunday Stamps!
