Jean-Michel Basquiat (December 22, 1960 – August 12, 1988) was a Haitian-American artist. Basquiat first achieved notoriety as part of SAMO, an informal graffiti group who wrote enigmatic epigrams in the cultural hotbed of the Lower East Side of Manhattan, New York City during the late 1970s where the hip hop, post-punk and street art movements had coalesced. By the 1980s he was exhibiting his Neo-expressionist and Primitivist paintings in galleries and museums internationally, but he died of a heroin overdose at the age of 27 in 1988. Basquiat sold his first painting in 1981, and by 1982, spurred by the Neo-Expressionist art boom, his work was in great demand. In 1985, he was featured on the cover of The New York Times Magazine in connection with an article on the newly exuberant international art market; this was unprecedented for an African-American artist, and for one so young. Since Basquiat’s death in 1988, his market has developed steadily – with a dramatic peak in 2007 when, at the height of the art market boom, the global auction volume for his work was over $115m.
