There was a marked difference between 'propaganda' posters produced by the transport companies during the two wars. Those published by the Underground Group in the Great War (1914-18) presented the conflict as an idealised struggle and urged men to enlist.
LT's war posters (1939-45) stressed the individual's role in helping the war effort at home, reinforced with examples from history and the Blitz In both cases, the approach taken reflected the wider poster campaigns of the British government.
