This semi-postal stamp from Luxembourg, issued shortly after World War II, depicts the ruins of Echternach Abbey, one of the country’s most historic monastic sites. The finely engraved black-and-white design captures the stark devastation inflicted during the Battle of the Bulge, making it a poignant postwar issue. The “+10c” surcharge supported national reconstruction efforts, adding charitable significance to the piece. It is a sought-after issue for collectors of European postwar history, architectural philately, and Luxembourg semi-postal series. Crisp lines and dramatic shading give this stamp exceptional visual depth.
