This classic 15 Francs definitive from Algeria features the iconic “Marianne à la Nef,” a symbol of the French Republic rendered in a bold scarlet shade. Issued during the 1950s under French administration, it was part of the standard postal series adapted for Algerian use with the inscription “RF – ALGERIE – RF.” Designed by Louis Muller and engraved by Jules Piel, the stamp shows Marianne crowned with oak leaves, representing strength and civic virtue. Postally used examples like yours carry strong historical interest as they document Algeria’s late-colonial postal period before independence in 1962.
