This striking Luxembourg stamp, issued in 1907, features a finely engraved portrait of Grand Duchess Marie-Adélaïde in green. Originally part of the definitive issue, this example bears the bold black “Officiel” overprint, designating it for official government use. Official overprints from Luxembourg are sought after due to their historical role in administration and their limited circulation compared to regular postal issues. The elegant typography of the overprint adds a distinct layer of appeal for specialized collectors of Luxembourg philately. A well-preserved piece like this enhances any collection focusing on early 20th-century European official issues.
