These 1920s posters for Japan's industrial expos had a whimsical, psychedelic vibe, not unlike Fritz Lang partying with Jules Verne in the Harajuku. In the 40s, this playfulness gave way to Orwellian styles that are militaristic, monochromatic, and scary.
What's absolutely incredible about this series of posters is that they convey the ideological evolution of Japanese society through industrial fair advertising - the designs go from freewheelingly futuristic to downright fascistic. Check out these stunning prints (and oodles more) at Pink Tentacle.
