Issued by Christmas Island in 1978, this elegant souvenir sheet commemorates the 25th anniversary of Queen Elizabeth II’s coronation in 1953. The central stamp features a portrait of the Queen framed within royal insignia, flanked by two symbolic images — the White Swan of Bohun, representing English heraldry linked to the royal lineage of Mary of Bohun and Henry IV, and the Abbott’s Booby, a rare bird species native to Christmas Island. The lower panel includes a stylized depiction of the coronation procession, with an explanatory text linking local and royal symbols. Printed by The House of Questa, this issue combines regal heritage with the island’s natural identity.
