Serbia 1918 Postage Due Stamp, Unissued
Serbia · 1918 · 50 Para
This postage due stamp features a large numeral '50' for the denomination, enclosed within an ornate, decorative frame. The design is simple and functional, with the Cyrillic inscription "ПОРТО МАРКА" (Porto Marka) indicating its purpose to collect unpaid postage. The stamp was printed but never officially issued for postal use.
Prepared during the final year of World War I, this stamp was intended for use in Serbia following its liberation. However, due to the subsequent formation of the Kingdom of Serbs, Croats and Slovenes (later Yugoslavia), these Serbian-specific issues were never put into circulation.
