This has been trumpeted as a huge show, an extensive career overview. It isn't. Comprising 19 rooms (many of the rooms at Tate Modern are tiny), it takes up a whole floor. It covers his activities as a hugely successful commercial artist ($100,000 in 1956 alone) and there are lots of interesting early illustrations. A court painter for the 20th century, his images of screen legends are the defining images of the media age, and the iconic Marilyns, Liz Taylors and Jackies, both grieving and grinning, are all here.
