This previously unpublished work is essential reading for anyone who has followed Marco Frascari’s scholarship and teachings over the last three decades.It also provides the perfect introduction for anyone new to his writings.As ever, Frascari does not offer prescriptive tools and frameworks to enact his theories of drawing and imagination; instead, he teaches how to build one’s own through individual practice.An illuminating introduction places the text in a wider context, providing the reader with a fascinating and important context and understanding to this posthumous work.Frascari's sketchbooks are reproduced faithfully in full colour to provide the reader with a remarkable insight into the design process of this influential mind.
