Nothing really new for cinephiles, but a nice overview of global poster design. It's not a "best of" compilation but rather more of a sampling of typical designs throughout the decades of cinema. Sprinkled with tidbits of information and notes about design and the poster artists.
When referring to the poster for the movie GUMMO, King does make the mistake of calling Xenia, Ohio, a "fictional" town. I'm sure the residents of Xenia would be surprised to hear they're imaginary. Minor quibbles like this aside, it's a pretty good book.
