Donald Duck image, 1944

In the Juno Beach Centre, Courseulles-sur-Mer, Normandy, France. Presumably a member of the Canadian forces that landed at Juno Beach in June1944 was responsible for this artwork. [I had to photograph this: Donald has always been my favourite cartoon character, alongside Sylvester the Cat.]
DD or Duplex Drive tanks, nicknamed "Donald Duck tanks" were a type of amphibious swimming tank developed by the British during the Second World War. The phrase is mostly used for the Duplex Drive variant of the M4 Sherman medium tank, that was used by the Western Allies during and after the Normandy Landings in June 1944. (Wikipedia.)
