I keep all my occupation and Plebiscite stamps (except Occupied Germany) in a single volume, alphabetically listed. Occupied Germany (Scott's 1-15N) are in their own binders.
I have been a collector of Poland Stamps for a long time and use the Minkus album. Near the end is a selection of Poland stamps overprinted S.O. 1920 which represent Eastern Silesia. The numbers go from 41 to 50 and I have up to 47. I have been going through a 3 volume Regent stamp album I used many years ago and some of the stamps were never transferred for one reason or another - that's my job now. Every once in a while I come up with something interesting. I found two overprinted Czech stamps overprinted SO 1920. I assume if I had a Minkus Czech album they would be in the back of that book. The area was actually divided between Poland and Czechoslovakia after WWI so dividing the stamps between the two areas makes sense since they were used in both areas. Do you collectors divide them up by country? I'm tempted to keep them together under Poland in some spare space - does this make sense and do any of you do the same under either country? I'm just curious!
