A classic Luxembourg provisional issue featuring the elegant engraved portrait of Grand Duchess Charlotte, originally printed as 10 centimes and officially surcharged to 7½ centimes to meet revised postal rates. The bold black overprint creates strong visual contrast against the deep carmine frame, making it a distinctive and collectible variety. Finely detailed line engraving and ornate borders reflect early 20th-century European craftsmanship. Popular with surcharge and Luxembourg specialists alike. A desirable addition to any Grand Duchy definitive or overprint collection.
