NEW YORK, NY.- After World War I, striking modern posters began to transform the stations of London’s Underground, the first subterranean railway system in the world. These posters were the crucial face of a pioneering public transport campaign for coherence and efficiency that also included station architecture, signage and timetables, buses and bus stops, train interiors, upholstery, and even public trash bins. The program is still recognized as a landmark in corporate design. The principal figure in this famous campaign was Frank Pick (1878–1941), who joined the Underground Group as an assistant in 1906 and became managing director of the newly formed London Passenger Transport Board in 1933. Pick commissioned Edward Johnston to design the system’s distinctive typeface—Johnston Sans (1916)—and roundel logo (1918)
