This attractive set from Christmas Island (Indian Ocean) highlights classic stamp designs combined with a portrait of Sir Rowland Hill (1795–1879), the pioneer of modern postal reform and the Penny Post system. Each 20c stamp features a different historic stamp motif, including early Australian issues, island map designs, marine life, and a festive angel stamp from 1969. The creative “stamp-on-stamp” layout celebrates both philatelic history and the postal heritage of Christmas Island. With vibrant colors and thematic variety, this issue is a charming addition for collectors interested in postal history, island territories, and classic stamp designs.
