This Luxembourg official stamp features a fine engraved portrait of Grand Duchess Marie-Adélaïde, issued in the early 20th century. Printed in an olive-brown shade, the design includes a crowned oval frame with the denomination “15 C” at the top corners and “LUXEMBOURG” boldly inscribed below. The overprint “Officiel” indicates its restricted use for government and administrative correspondence, making it part of the scarce Luxembourg official issues.

Official stamps from Luxembourg are highly sought after due to their limited circulation and historical connection to the reign of Grand Duchess Marie-Adélaïde, who ruled from 1912 to 1919. This issue reflects both political history and classic European stamp engraving artistry.
