I was on a stamp fair and that's where I found the following stamps of Tanzania.
They are CTO - unfortunatly - but from some countries that's more or less the only way to obtain the emitted stamps.
We see a weird combiation of prehistorical animals
5/- Jurasic Brontosaurus
and 100/- Stegosaurus
and, the other values shows animals that are still alive:
8/- Tiger (strange, as tigers do not live in Africa)
12/- Orang-Utang (living in Sumatra and Borneo)
The fact that they are all CTO makes the whole set even less interesting.
However, I can't keep them away from my blog, as the 'oddness' is there...
