This striking Luxembourg 10 centimes green issue from 1907 features the portrait of Grand Duchess Marie-Adélaïde, finely engraved and framed with a regal crown emblem. The stamp bears the elegant black overprint “Officiel”, designating its use for government correspondence. Official stamps like this were printed in limited numbers, making them highly desirable for collectors of Luxembourg’s philatelic history. Its crisp green color and ornate calligraphic overprint highlight the nation’s early 20th-century postal heritage. A valuable piece for those seeking specialized overprint issues or early Luxembourg classics.
