This book explores so-called 'witty thinking' - arguably the most entertaining area of graphic design. Witty thinking is playfulness with ideas, words playing against images, and unexpected connections prompting new insights. It is clever thinking, not funny drawing.

A Smile in the Mind analyses the intricate thought processes behind the apparently forward images. It shows how to make the case for witty solutions and, through a series of in-depth interviews with the world's top designers, suggests how to get inspiration. Gathering together the best examples of graphic wit over the past three decades, this book includes work from over 300 designers in the USA, Britain, Europe and Japan. Written with insight and a subtle lightness of touch, it offers designers a friendly read, a helpful sourcebook and a dynamic trigger for ideas.
