Issued by Portugal, this striking 1$00 definitive features a stylized caravela portuguesa—the emblematic sailing ship of the Age of Discoveries—set against a sky of stars. Designed by Martins Barata, the stamp belongs to the long-running “Navegadores / Caravel” series, one of Portugal’s most iconic philatelic themes. Its rich carmine-lake tone, bold engraving, and rhythmic wave pattern make it a favourite among classic Portuguese collectors. Postally used examples like this one often show sharp cancellations that complement the design without obscuring key details.
