This is a truly excellent and enjoyable book,filled with high quality images and clear concise text,free from waffle. It highlights the value of sketching and other eperiments in the creation of a work of art. it shows why a sketchbook is an artits most valuable posession. The contrasting and varied range of artists reviewed shows that there are many varied approaches to visual creativity. I have no hesitation, as a designer and design teacher of over 40 years experience, in reccomending this book to anyone with an interest in this area.
