This WWI recruitment poster from 1915 shows soldiers firing from a trench, and a vignette of players on a soccer pitch. It reads: 'Young men of Britain! The Germans said you were not in earnest. Extract from Frankfurter Zeitung: 'The young Britons prefer to exercise their long limbs on the football ground, rather than to expose them to any sort of risk in the service of their country.' 'We knew you'd come - and give them the lie!' Play the greater game and join the football battalion.'
