Denmark 5 Øre Postage Due Stamp (1921)

Denmark · 1921 · 5 Øre

This is a postage due stamp, known as a 'Porto' stamp in Danish. The design is purely functional, featuring the large numeral '5' to indicate the amount due, framed by ornate scrollwork. The word 'PORTO' is prominently displayed at the top, with 'DANMARK' at the bottom.

Issued in 1921, this stamp was used to collect insufficient postage from the recipient of a letter. This design type was part of a long-running series first introduced in 1902 and continued with variations for several decades.
