This classic Luxembourg stamp, denominated 25 centimes and printed in deep brown, features the profile portrait of Grand Duchess Marie-Adélaïde framed by a laurel design and surmounted by a royal crown. Originally issued in the early 1900s (circa 1906–1914) as part of the definitive series, this variety bears the “Officiel” overprint in elegant black script, denoting its use for official government correspondence rather than public postal service.

The detailed engraving and regal composition reflect Luxembourg’s strong royal symbolism and careful typographic balance typical of early 20th-century issues. Official stamps like this one are highly regarded among collectors for their rarity, particularly in fine mint or lightly used condition.
