Yayoi Kusama with Cornell 1970
(he looks a little like he's choking her, but she looks happy)
Yayoi Kusama Age 10 1939
Blouin Artinfo has more photos of Kusama (that's where I got these).
Link to my recent boingboing essay on the book about Joseph Cornell, Utopia Parkway.
Kusama and her relationship with Cornell is mentioned in the book.
The photo (above) was taken in 1970, he died in 1972.
