This striking Tristan da Cunha set pays tribute to Sir Rowland Hill (1795–1879), the pioneer of the modern postal system. Each stamp creatively reproduces classic St. Helena issues with historical overprints used by Tristan da Cunha before its own definitive releases. The designs feature King George VI, Queen Elizabeth II, and the famous 5s black “Inaccessible Island Rail” vignette, all framed in bold 1970s colour panels. The set beautifully reflects the island’s early postal heritage, its reliance on St. Helena stamps, and the evolution toward its own independent postal identity—making it a highly appealing addition for collectors of British Overseas Territories and postal history themes.
