Others involved in the planning of the early posters included: John Hilton, Professor of Industrial Relations at Cambridge University, responsible overall as Director of Home Publicity; William Surrey Dane, managing director at Odhams Press; Gervas Huxley, former head of publicity for the Empire Marketing Board; William Codling, controller of HMSO; Harold Nicolson, MP (often misspelled as "Nicholson" in paperwork); W. Ernest Wallcousins was the artist tasked with creating the poster designs.
Detailed planning for the posters had started in April 1939 and the eventual designs were prepared after meetings between officials from the Ministry of Information and HM Treasury on 26 June 1939 and between officials from the Ministry of Information and HMSO on 27 June 1939.
The leaflet begins "If invasion comes..." and exhorts the populace to "Stand Firm" and "Carry On".
The two phrases do not appear in one sentence, as they applied to different segments of the population depending on their circumstances, with those civilians finding themselves in areas of fighting ordered to stand firm (i.e., stay put) and those not in areas of fighting ordered to carry on (i.e., continue vital war work).
