Michael Crichton’s collection of art – including Pablo Picasso, Andy Warhol and Jasper Johns – is going on sale. The author died in November 2008 at the age of 66.

Four pieces from Crichton’s collection valued at $32 million — including an iconic Johns Stars and Stripes “Flag” painting that once hung in the writer’s Beverly Hills bedroom — went on display Friday before being auctioned by Christie’s in New York in May.
