The greater kudu stamp shows a Khomas Highlands landscape (around 40 kilometres west of Windhoek) with the Haiquap River (an ephemeral river only carrying water intermittently for a very short period of the year) as a central feature. The hills do not have individual names.
The Eland stamp shows a broad-leaved woodland landscape in the Kavango region in north-eastern Namibia, with a false mopane tree (Guibourtia coleosperma) as a central feature. The trunk and leaves with some sky showing through them may at a fleeting glance give the impression of a waterfall, but there is no waterfall in the landscape, which is extremely flat and without surface water, consisting mostly of dry woodland on Kalahari sand.
Many thanks to Helge Denker (designer of this stamp series) for the detailed information concerning the landscape in the background of the stamps.
