Issued by Belgium in 1969 for Dag van de Postzegel / Journée du Timbre (Stamp Day), this striking 3 Franc commemorative features a bright red electric postal train speeding along the rails. The design celebrates Belgium’s long tradition of efficient railway mail transport, symbolised by the gold postal emblem on the locomotive’s front. Rich color printing, dynamic perspective, and fine engraving make this a desirable thematic item for collectors of transportation, trains, and postal history. A classic mid-20th-century Belgian issue with strong visual appeal.
