Pink Tentacle [yup, you heard right] has a great round-up of simply terrific examples of vintage graphic design from an era ripe with social change and even emergence of the influence of Western culture.
In the 1920s and 1930s, Japan embraced new forms of graphic design as waves of social change swept across the nation. This collection of posters, magazine covers and advertisements offer a glimpse at some of the prevailing tendencies in a society transformed by the growth of modern industry and technology, the popularity of Western art and culture, and the emergence of leftist political thought.
