Kingdom of Yugoslavia

,1, 3, P1,

Ravna Gora. Cover with three values affixed and cancelled by rubber canceller "POŠTA / Jugoslovenske vojske u otaćbini / gorski štab" (= POST / of Yugoslav Army in Homeland / Mountain Headquarters) and the coat-of-arms of Kingdom of Yugoslavia.  Dated 9/5 (1944) and code number of headquarters is written in manuscript. There is also a strike of Zenica postmark (9.5.44)  on the cover, possibly as "arrival cancellation", but no address is written (sic !). This cancellation is unknown to me, the cover is sold "as is". From Dragutin Marjanović collection.
