Cyril Kenneth Bird (Fougasse) produced a number of public information posters for London Transport between 1925 and 1945. He used humour to communicate with the Passengers and present everyday instructions and advice in an eye-catching and memorable way. This poster illustrates the paternal role undertaken by the Underground during the war. The problem of overcrowding had increased, and posters like these helped establish a code of conduct that would keep Passengers safe and services running smoothly. Fougasse reminds Passengers to move down the carriage in order to let more people board. The slogan 'Ticket down the car', which appeared on numerous public information posters, formed part of an emerging Underground etiquette.
