This striking 9d commemorative from the United Kingdom’s 1965 “Battle of Britain” issue honors the pivotal 1940 air campaign fought over British skies. The design captures the tension and heroism of the event, showing ground observers and aircraft amidst dramatic orange-and-blue battle imagery, paired with a classic portrait of Queen Elizabeth II at right. Issued to mark 25 years since the battle, it remains a key WWII thematic item and is prized for its powerful modernist artwork by David Gentleman. A must-have for collectors of wartime postal history and mid-1960s British commemoratives.
