This classic 1930 Greek commemorative stamp honors Petrobey Mavromichalis, a leading figure of the Greek War of Independence and head of the Maniot resistance. Issued to mark the 100th anniversary of Greek independence (1830–1930), the stamp shows a finely engraved brown portrait framed with ornamental borders typical of early 20th-century Greek design. Printed by Perkins Bacon & Co., London, the issue is admired for its crisp line engraving and historical significance. A popular piece among Hellenic history collectors, it often appears with clear circular date cancellations, as seen here.
