This 1994 Belgian commemorative stamp depicts Duke John I of Brabant, celebrated as a chivalric hero of the Low Countries. Shown in full medieval armour, he engages in a vivid tournament scene, rendered after historical manuscript imagery. The contrasting heraldic colours—black-gold lion and red-gold lion—emphasize noble lineage and regional identity. The detailed background of mounted knights gives the stamp strong artistic depth. A fine thematic issue for collectors of medieval history, European nobility, and heraldry on stamps.
