Penguin made this book for a special occasion. The publisher celebrated its 70th birthday. In this book you will find how the covers of their books evolved during those 7 decades. Some people have shelves full of books by this publisher. And only this publisher. The books almost seem to have become a piece of design themselves. This book will tell you why people love those orange paperbacks. You can take a look and/or order it here (US) or here (UK).
