This striking 20c + 10c semi-postal stamp from Luxembourg was issued in 1945 to raise funds for post-war reconstruction. It depicts the bomb-damaged remains of the Benedictine Abbey of Echternach, one of the country’s most historic religious sites, founded by St. Willibrord in the 7th century. The detailed engraving, rendered in deep black, captures the solemn beauty of the ruins after World War II. The surtax of 10 centimes went toward relief and rebuilding efforts, making it both a historical and humanitarian issue cherished by collectors.
