Issued by Antigua and Barbuda, this 12-cent definitive features the historic cannons of Fort James, a key colonial coastal battery guarding St. John’s harbour. The engraved brown design shows a line of artillery pieces facing the sea, symbolizing the island’s strategic maritime defence. The portrait of Queen Elizabeth II adds classic Commonwealth character to the layout. Fine line engraving and strong architectural detail make this a visually rich mid-century issue. A desirable thematic piece for collectors of forts, military history, or Caribbean colonies. Scarcer in clean, well-centered mint condition.
