This 5p commemorative from Tristan da Cunha (United Kingdom territory) was issued in 1979 to mark the centenary of Sir Rowland Hill’s death (1795–1879), honoring the founder of the modern postage system. The design incorporates a reproduction of the classic St. Helena King George VI “Colony’s Badge” stamp with an overprint reading “TRISTAN DA CUNHA”, a nod to early postal dependencies in the South Atlantic. The original 10/- badge stamp—depicting a sailing ship approaching rugged coastal cliffs—remains a celebrated colonial icon. This commemorative blends postal history, portraiture, and heritage into a refined modern issue, ideal for collectors of British territories and Rowland Hill memorabilia.
