The National Museum of Art, Osaka: The Complete Posters Exhibition http://www.nmao.go.jp/english/b3_exhi_beginning_yokoo.html
Tadanori Yokoo began producing posters while attending high school in his hometown of Nishiwaki. Then, following stints at the Kobe Shimbun newspaper, the National Advertising Research Center, and after moving to Tokyo in 1960, the Nippon Design Center, Yokoo joined the Japan Advertising Artists Club at the tender age of 22. In the mid-60s, through his relationships with Juro Kara and Shuji Terayama, Yokoo suddenly rose to prominence through works such as Koshi-maki Osen and La Marie Vison. At the same time, his illustrations for magazines such as Heibon Punch and Hanashi no Tokushu made him a darling of the media. Yokoo's posters, which while reflecting post-war Japanese society, have been burned into our brains as unforgettable memories of the era. They are also notable for the fact that rather than following foreign trends, they display a unique sense of Japanese graphic design. Yokoo's creative activities later expanding to include a wide range of fields such as painting and literature, but as he continued to produce posters throughout his career, the poster format functions as the core of his work as an artist.
