This 1991 commemorative stamp from Belgium celebrates “Stamp Day” (Dag van de Postzegel / Journée du Timbre), honoring the art and heritage of philately. The design features the modern facilities of the stamp printing works in Mechelen (Zegeldrukkerij Mechelen / Imprimerie du Timbre Malines), a key center of Belgian stamp production. Its clean architectural illustration reflects the technological advancement of stamp printing during the late 20th century. The bilingual inscription highlights Belgium’s cultural duality, adding further appeal for collectors. A fine thematic piece for those interested in postal history, printing, and Europa-region issues.
