Postage Due Stamp, Bosnia and Herzegovina

Bosnia and Herzegovina · 1916 · 2 Heller

This is a postage due stamp, indicated by the large numeral '2' and the text 'PORTO'. The design is purely functional, featuring the denomination prominently within an ornate, rectangular frame. The stamp's purpose was to collect insufficient postage from the recipient of a mail item.

Issued during the Austro-Hungarian administration of Bosnia and Herzegovina, this stamp reflects the typographic and administrative style of the era, just two years before the empire's dissolution following World War I.
