This four-stamp 37c set from Australia (1987) commemorates the First Fleet’s historic stopover at Rio de Janeiro in August 1787, an essential resupply stage on the voyage to New South Wales. Each stamp features finely illustrated scenes capturing the cultural encounters, vibrant harbour activity, local markets, and tropical wildlife seen by the Fleet during its brief stay. The set is prized by collectors for its narrative artwork, crisp detailing, and its role within the broader First Fleet commemorative issues. A desirable thematic group for collectors of Australian history, maritime exploration, and 18th-century colonial voyages.
