Issued in 1977, this striking five-stamp series commemorates the Silver Jubilee of Queen Elizabeth II, marking 25 years since her accession in 1952. Each design features the crowned profile of the Queen set within a bold octagonal frame, flanked by the royal cypher “E II R” and the years 1952–1977. The denominations — 8½p, 9p, 10p, 11p, and 13p — are printed in distinctive color combinations including blue, lilac, bronze, pink, and yellow. Designed by Jeffery Matthews, these stamps exemplify modern British philatelic design celebrating continuity and monarchy.
