Take a moment to have a look through these too cool posters, which appeared in Tokyo subways between 1976-1982 to encourage passengers to remember their manners. The posters have used famous characters for inspiration, such as Superman, Space Invaders, Charlie Chaplin, John Wayne, Marilyn Monroe and artwork from everyone’s favourite short French Post-Impressionist Henri de Toulouse-Lautrec. Thanks to Adland for bringing these to my attention, some visual sunshine for a grey afternoon. Check the Superman one… Kryptonite flavoured gum obviously.
