Check out this new book from Lauren King Publishing: 

 "A fantastic source of inspiration, the book gives insight into the inner workings and private inspiration of creatives from the world of advertising, design, graphic design, fashion design, art, street art, and illustration. Intimate and often unseen, sketchbooks document the sources of inspiration as well as the journey to final execution. Providing a showcase of ideas, the sketchbooks themselves are complemented by interviews where the artists explain how they use their sketchbooks and how these relate to finished works, giving readers a direct and unmediated insight into the process of research and creation."
