190-(?) Russian "Die Post In Finnland." - Information Desired & Lets See All 40 Images Of Sheet.

Explanation for riding cattle rather than horses:

" The pre-colonial period of Namibia ended in 1884, when the German Imperial government proclaimed Namibia as the Protectorate of German South-West Africa. The primary mode of transport at this time was by riding oxen and ox-wagons (Figure 1), whilst horses were only used to a limited extent because of the presence of African horse sickness (AHS). However, as the establishment of mission stations, mining operations and trading centres progressed, more horses were introduced, with the first horses reaching central Namibia in 1820.1 The first reported animal disease was anthrax in 1842, followed by AHS in the same year and contagious bovine pleuropneumonia (CBPP) in 1856. The biggest impact, with heavy losses, was caused by CBPP and later rinderpest (1897)."

Presumably each set of 48 stamps was printed with a different company, so there are literally hundreds of stamps to collect. Hope that helps shed some light on these cinderellas.

Glad this was solved, especially in such thorough fashion.
I'd suggest to everyone who may read this, to strongly consider posting measurements in mm, instead of inches. Only three countries still officially use Imperial, so you either lock out or inconvenience about 6.5 billion people (and potential respondents) when you use it instead of metric. I guess maybe Imperial makes sense for older US issues, beyond that I can't think of a good argument to use it. My two cents.

Imperial weights and measures are still widely used in the UK, and not just by grumpy old men like me.

Here are a few more examples. I'm particular to the "Canada" stamps.
