The UK edition of William Gompertz' popular survey of modern art, What Are You Looking At? The Surprising, Shocking, and Sometimes Strange Story of 150 Years of Modern Art, has this wonderful pull-out "map of modern art." The map illustrates the relationships between various modern art movements, and shows the development of those movements through time from left to right. The map uses the design of the famous London Tube map as its inspiration, and the different tube lines represent the various movements, and the "tube stops" are artists in those movements. Gompertz is a former board director of the Tate Gallery, and currently the BBC arts editor. Check out the Pop Art-inspired UK and US book covers below. It's such a shame that the US edition doesn't include the map! You can buy a copy of it from the Penguin Books UK site.
