Incredible colorized images of Britain after World War I Looking awkward in his top hat and great coat, Prime Minister Neville Chamberlain gives a pained smile as a poppy is pinned to his lapel in 1937. Less than two years later, Chamberlain's policy of appeasement towards Nazi Germany had failed spectacularly and Britain had declared war. The photo is among a set released by the TopFoto archives and then colorized by Welsh electrician Royston Leonard to mark the Royal British Legion's 100th birthday. The Royal British Legion was formed on May 15, 1921, after the First World War to fight the injustices faced by servicemen when they returned home from the conflict. It still provides life-changing support to the needs of the armed forces community 100 years on.
