1925 Denmark 10 Øre Airmail Trial Proof

Denmark · 1925 · 10 Øre

The stamp features a stylized airplane soaring above a horse, with 'DANMARK' at the top and '10 ØRE' at the bottom. This is an unperforated red trial color proof of the design.

This trial proof is for Denmark's 1925 definitive airmail series, reflecting the growing importance of aviation for postal transport in the early 20th century. It represents an early stage in the development of dedicated airmail services.
