This attractive pair of Belgian definitive stamps features the formal portrait of the national monarch (King Albert II era design), both denominated at 16 francs. The set presents two distinct printings: a natural-color portrait version and a monochrome blue variant, illustrating Belgium’s modern definitive design evolution. The clean typography, national emblem, and formal official portrait make these stamps an essential addition to any Belgium definitive or European royalty collection. Well-preserved examples such as this pair are especially appreciated when collected together to showcase printing variations. A fine collector’s item representing late-20th-century Belgian postal issues.
