This Belgian semi-postal stamp portrays Margaret of Parma, the influential 16th-century regent of the Netherlands under King Philip II of Spain. Issued in a refined sepia-brown tone, it shows her in elaborate Renaissance attire, framed by an ornate classical border. The denomination 50c + 10c indicates a charitable surcharge, typical of Belgium’s wartime semi-postal issues. This piece belongs to a historical personalities series celebrating figures tied to the Low Countries’ past. A desirable item for collectors of Renaissance history, Belgian semi-postals, and European royalty.
