King Albert I, 1915 Overprint Issue

Belgium · 1915 · 10c

This stamp features a portrait of King Albert I, known as the 'Soldier King' for his leadership during World War I. The design is based on the 1912 definitive series but is distinguished by a red cross overprint. This overprint signified that the proceeds from the stamp's sale, above its postal value, would be donated to the Red Cross to support war relief efforts.

Issued during the German occupation of Belgium in World War I, this semi-postal stamp was a crucial fundraising tool for the Belgian Red Cross, providing aid to wounded soldiers and civilians.
