Postage Due Stamp, Black Numeral on Yellow

Bosnia and Herzegovina · 1904 · 1 Heller

This is a postage due stamp, designed to indicate the amount of postage to be collected from the recipient of underpaid mail. The design is purely functional, featuring a large black numeral '1' indicating the value of 1 Heller, set against a solid yellow background. The text 'Bosnien-Hercegovina' and 'Porto' (Postage) frame the central value.

Issued during the Austro-Hungarian administration of Bosnia and Herzegovina, these stamps were used to collect fees for mail that lacked sufficient postage. Their simple, utilitarian design was common for postage due stamps of the era.
