I use this book when I teach design process in graphic design. It's a great book for generating ads and ideas. Granted, it's 25 years old; however, Photoshop enhances but does replace a good idea. Garchik lays out his process with no-nonsense clarity. Everyone I have taught his technique understands it. It's also great for getting a linear thinker to generate creative ideas. It contains good (albeit slightly dated) images that support his healthy amount of approaches to generate advertisements. Plus, you can pick up a hardcover cheap!
