And moving forth with Nigerian definitive stamps of 1973, here are the most commonly met values of 5 and 10 kip. Based on my limited experience, these seem to be also the ones with most varieties.
5K Cattle Ranching
This stamp exist both in photogravure (unwatermarked) and offset printing (both unwatermarked and watermarked paper).
According to Michel the photogravure version is found on two varieties: dark and yellow green fields. However, I’ve got an offset stamp with yellow field
And here’s some heavy printing on photogravure stamp. Notice how the details of grass and cattle have merged into shapeless mass, and the manufacturer inscription at the bottom in unreadable:
10K Yankari Game Reserve
This stamp exist both in photogravure (unwatermarked) and offset printing (both unwatermarked and watermarked paper). According to Michel the photogravure stamp comes in two varieties, where the right side cheetah has either white or black belly fur.
And then for the varieties I’ve stumbled upon. First, here’s an offset stamp with damaged letter “E” (in inscription “YANKARI GAME RESERVE”). Also the other letters in word RESERVE seem a bit mixed up.
And then another offset variety where black has been printed below other colors:
Based on the limited samples I have, I’d say that 10k stamp has got likely the most color variations in this series. Below is one example:
And here’s another slightly different looking pair. Put special notice on the latter stamp, and especially on the tree where cheetah is standing. A lot of the (black) details have mysteriously vanished:
As usual, please feel free to share your comments/opinions/observations on these stamps.
