A collection of fifty case studies in brief of advertising and design work preformed by Pentagram Design. The book is a bit more than most advertising book that merely through a serious of their "best" ads at the reader. Instead, they go into depth about the theory and principles behind the way they designed, including some analysis about what worked and what did not. This is not a book that one would sit down and read, rather it is a book to flip through and stow away the images with an increase in knowledge about good design.
Interesting tidbit: Pentagram Design was responsible for the Celebration, Florida. The special city built and maintained by Disney.
