I was given the following postcard advertising the Okamoto Taro Museum in Kawasaki (岡本太郎美術館), so I thought I'd drop it in here before I lose it (and in case it's of interest to others).
Wikipedia has a page on the man - which begins with this bit of text:
"Tarō Okamoto (岡本太郎, Okamoto Tarō) (February 26, 1911–January 7, 1996) was a Japanese artist noted for his abstract and avant-garde paintings and sculpture.
"He studied at Panthéon-Sorbonne in the 1930s, and made many great art works after WW II. He was a prolific artist and writer until his death, and has exerted considerable influence on Japanese society."
