Japanese artist Taro Okamoto (1911-1996) was noted for his abstract and avant-garde paintings and sculpture. The combination of shapes and colours in these playing cards creates a vibrant and eye-catching surreal effect. One of Okamoto's famous works, Tower of the Sun, became the symbol of Expo '70 in Suita, Osaka, 1970. During the 1970s Okamoto was also working as a muralist and designer whilst continuing to create and exhibit new works. His mural "The Myth of Tomorrow" (2008) depicts a human figure being hit by an atomic bomb.
