Following news of Princess Elizabeth's engagement to Philip Mountbatten in 1949, thousands of tourists from across the pond came to London and helped lift the wartime gloom.
Elizabeth was married on 20 November 1947 and just a year later the 1948 Olympic Games were held in London - drawing in millions from across the world.
After her marriage the princess was tasked with aiding Britain's economic recovery from the war by encouraging more and more tourists from the US to visit.
