This striking 10 stotinki stamp from Bulgaria, issued during 1915–1916, commemorates the so-called “War of Liberation” (Освободителна Война), Bulgaria’s WWI military campaigns. Printed in a rich carmine-red, it features a finely engraved landscape of the Šar Mountain (Шаръ Пл.), a symbolic Balkan peak tied to Bulgarian national aspirations during the war. The design combines patriotic imagery with elegant ornamental framing and bilingual date panels (1915–1916). A historically significant wartime issue, it represents one of Bulgaria’s most collectible WWI-era commemoratives—valued for its sharp engraving, political context, and clean typographic style.
