This elegant definitive series from Belgium features the left-facing profile of King Baudouin I, a design that became iconic in Belgian philately throughout the 1970s and 1980s. The minimalist layout highlights the monarch’s refined portrait, framed vertically by the bilingual inscription “BELGIË – BELGIQUE.” Shown here are denominations of 17F, 22F, and 25F in shades of violet and grey-black, engraved by H. Edel and printed in photogravure. These stamps reflect Belgium’s classic modernist design aesthetic during Baudouin’s reign.
