This Belgian stamp, issued in 1976 with a face value of 6.50 francs, was released to mark the Journée du Timbre / Dag van de Postzegel (Stamp Day). The design depicts the Brussels Central Post Office Building, a striking modernist structure representing Belgium’s postwar architectural progress and the efficiency of its postal service. Executed in monochrome engraving, the image captures the detailed gridwork and symmetry of the building’s façade.

Designed by C. Slabbinck and engraved by H. Vandeveld, this issue honors Belgium’s rich philatelic heritage while celebrating the modernization of communication infrastructure in the 1970s.
