One of the more unusual war memorials at the Imperial War Museum is this London General omnibus, known as ‘Ole Bill’. Ole Bill was used during the First World War to transport troops on the Western Front. It returned to commerical use after the war, but was later retired and became a permanent memorial to the role played by London buses in the First World War.
This photograph from Armistice Day, 1926, shows the bus outside the Imperial War Museum in South Kensington, where the museum was located at the time. Ole Bill joined the museum collections in 1970.
