This classic Luxembourg official stamp features the finely engraved profile of Grand Duchess Charlotte, rendered in deep green with exceptional detail. The elegant “Officiel” overprint designates government-use status, adding sought-after postal-history value. Issued during the 1930s, these overprinted definitives are desirable for their crisp typography and limited administrative circulation. A strong example for collectors of European monarchs, official service issues, or Luxembourg classic definitives. Ideal for a well-curated Luxembourg collection.
