This commemorative pair from Greece (Hellas), issued in 1977, honors the 150th anniversary of the Battle of Navarino (1827), a decisive naval victory that secured Greek independence.
The Δρ 7 stamp features the three Allied admirals—Comte Van Heyden (Russia), Sir Edward Codrington (Britain), and Comte de Rigny (France)—whose combined fleets defeated the Ottoman–Egyptian navy. The Δρ 4 stamp presents a dramatic depiction of the naval battle, rendered in a classic monochrome style that captures the intensity of the engagement.
A meaningful addition for collectors of Greek history, naval warfare, and independence commemoratives, this duo represents one of the pivotal moments that shaped modern Greece.
