Postage Due Stamp, Numeral in Oval Frame

Croatia · 1918 · 2f

This is Croatia's first postage due stamp, featuring a simple yet functional design. The numeral '2' is prominently displayed within a decorative oval frame, indicating the amount to be collected upon delivery. The inscription 'PORTO' at the top clearly marks its purpose as a postage due stamp.

Issued in 1918, this stamp marks a significant moment as Croatia established its own postal system following the dissolution of the Austro-Hungarian Empire at the end of World War I.
