I have (see below for that story) this 2" x 3 15/16ths" multi-color cinderella about which I know little:
1. Russian due to flag
2. Circa 1900 due to when Russia last controlled Finland.
3. Lapps (now known as Sami or Saami) in their reindeer sleigh.
4. The oblong label (pink-orange here) area on a Russian cinderella was often meant to have an over print of some type of propaganda.
UPDATE (Edit): Seems produced in Germany in sheets of 40 different designs all with the theme of The Mail (or Post) in some geographic area, such as Finland, Samoa, Turkey, Germany. Perhaps all 40 designs can be posted here as they surface. Of all the images I have seen so far (few) all are perforated, except for one example which may have lost its perfs due to close scissor trimming. The oblong area is blank or has what looks to be commercial business information (I don't read German).
What is it? How was it used or what was its intended function. Year(s) of production/use? Any with printing in the oblong area? What if any monetary value and the publication or market which establishes the amount? Other versions?
And, of course, where can I find more?

The story:
After 100+ years of rattling around in the world, it landed in India and was posted on
eBay. I excitedly purchased it and paid for it. Seller then asks me if I would cancel the sale of the many items I purchased in addition to this cinderella because there was now a blockade of mail to the USA issued by the Indian Government to extend several months through at least January 31, 2022. Ah, no! Seller held my material and my payment months but finally shipped it, arriving in my hands long after my family members from the area could still tell me about it.
