Poster; Underground day make your choice, August bank holiday, by Charles Sharland, 1914

This poster was commissioned by the Underground Electric Railway Company in 1914. It was designed by Charles Sharland to promote travel in and around London on the August bank holiday, renamed here 'Underground Day'.
The use of the bar and disc, later to become standardised and known as the roundel, is an excellent example of the Underground's early experimentation with its trademark. As Londoners decided which bank holiday excursion to make, politicians were making more serious decisions about the future of Europe. By the end of the week, Britain was at war with Germany.
