Original poster, published by the Railway Executive Committee, who ran the railways from the start of WW2 in 1939, until nationalisation created British Railways in 1948

Born in Yarmouth, Reginald Mayes’ career began in the design studio of the Eastern Daily Press in Norwich. He moved to London where he designed water marks for paper manufacturers and studied life drawing at the Regent Street Polytechnic and Lithography under Gardiner, Clive. In the early 1930s he became chief staff artist at the London Midland and Scottish Railway public relations department, designing leaflets and posters. In the Second World War, Mayes produced a wide range of anti-travel and propaganda posters for the Railway Executive Committee. They discouraged railway travel with some humorous slogans such as ‘The signal is against holiday travel this Easter’. After the war he did freelance work before retiring to Kent where he relaxed painting landscapes.
