Crichton is probably best known for his books - one of which was Jurassic Park - and for being the creator of ER. His interest in art dates back to the 70's and he collected works right up to his death late last year. He was best friends with Jasper Johns and interested in other artists such as Lichtenstein and Rauschenberg.
In 1974 he bought Jasper Johns' Flag which hung in his bedroom all his life and few people have ever seen this painting, so it was an exciting event for it to now be seen in public.
Below are some of his other works that sold last night
Warhol, Mao: $2.3m
Roy Lichtenstein, figures in landscape: $4.3m
Robert Rauschenberg, Studio painting: $11m
Richard Prince, Cowboy: $600k
