This historic stamp from Luxembourg was issued in 1939 to commemorate the 1200th anniversary of the death of St. Willibrord (739–1939), the missionary credited with founding the Abbey of Echternach. The design shows the saint in episcopal robes holding a crozier and book, with symbolic objects and ecclesiastical imagery beside him. The inscription “Echternach – Saunt Willambrord” references the famous abbey and pilgrimage center associated with the saint. Printed in an elegant engraved style by Joh. Enschedé en Zonen, the stamp carries a 35c + 10c semi-postal denomination, where the surcharge supported charitable causes. Its classic typography and strong religious symbolism make it a notable Luxembourg commemorative for thematic collectors.
