Sweden. Collection cover on leaves. A large study collection nice mounted on pages of the Mu 1 and Mu 2 issues, consisting of used military letters 1922–1928 with a lot of different fieldpost cancellations. These issues were rationed and used only when there was field service traning about three weeks each year. Otherwise invalid to use. Something for the specialist but also for a collector wishing to study these issues and usages. Also some other documentary material. High catalogue value. Please inspect! (21). Fine quality.
