This pair of definitive stamps from Belgium features the official portrait of King Albert II, issued for everyday postal use in the 16-franc denomination. The set includes two design variations: a monochrome blue portrait and a later multicolour photographic version, reflecting the evolution of Belgian definitive stamp printing styles during the late 20th century. These stamps were widely  circulated and are collected both as standard definitives and as part of specialised Belgian monarchy collections. Well-centred examples with clean perforations are desirable for collectors assembling complete Albert II definitive series. The contrasting colour formats make this pair especially attractive for comparative display pages.
