This classic Luxembourg definitive stamp features the elegant left-facing profile of Grand Duchess Charlotte, one of the most respected national figures in Luxembourg’s history. The finely engraved portrait with crown emblem symbolizes stability and national identity during the mid-20th century period. High-value definitives such as the 10 Francs were primarily used for heavier domestic or international postal rates, making genuinely postally used examples desirable among collectors. Its clean monochrome design reflects traditional European engraving excellence and remains a cornerstone issue for Luxembourg collections.
