Forerunner of the 1945 Zagreb provisional issue, letter sent from Nova Gradiška (30.V.45) to Zagreb, free of charge as for the military person, canceled as registered, censored by the military censor in Nova Gradiška. Very interesting promotional sticker: "Sve snage za obnovu saobraćaja" - "All forces for the reconstruction of traffic".
Back side with a rare Nova Gradiška National Liberation Committee cancellation.
