The four hundred marks reproduced in this book represent the diverse array of identity work produced by Pentagram's partners, past and present, since the company was founded in 1972. Over the past four decades, Pentagram has designed marks for large corporations and small businesses, government agencies and non-profit institutions, clubs and societies, and even individuals, all of whom were seeking a representative symbol to appear on letterhead and books, buildings and websites, and everywhere else imaginable.

Previously only distributed in a limited edition, this invaluable book is now made available in a paperback version and will provide inspiration for all graphic designers working on identity projects.
