The Battle of the North Cape, UK postmark

On this cover is a stamp showing Stonehenge from a 1990 series about astronomy, a pair of stamps from a 1991 set that commemorates the Ordnance Survey, a 2023 Christmas stamp and a King Charles low-value definitive. The postmark commemorates the 80th anniversary of the Battle of the North Cape: one of the last big-gun navel battles of WWII. It ended with the sinking of the German battleship Scharnhorst off the northern cape of Norway on 26 December 1943 by the HMS Duke of York and other supporting vessels.
