Issued by the Bailiwick of Guernsey in 1977, this elegant two-stamp set commemorates the Silver Jubilee of Queen Elizabeth II’s accession to the throne. Designed by R. Granger Barrett and printed by Courvoisier, the 7p (blue) and 35p (purple) stamps depict refined portraits of the Queen wearing her royal regalia and diamond tiara. The rich colors and fine engraving highlight the dignity of the British monarchy while celebrating 25 years of dedicated reign. A significant philatelic issue marking an important royal milestone.
