Nature is a best source to give one relaxation and rejuvenation from the drudgery. You get fascinated listening to naturalists and you get mesimerised by the photography that depicts the nature and the tranquility it has. Having little accessibility to nature, surrounded by sterile world, i preferred to collect postal stamps to watch the spectacular nature that is far from me.
And i just enjoy watching these creatures on stamps !
Here are two of the national parks of Namibia that i have on stamps.
Brandberg National Park
Centenary of Etosha National Park
