The Sketch book provides a readily available support for anyone to put down on paper one's thoughts, ideas, notes. Sketch books are highly personalized and eventually result in interesting compilations of text, scribbles, simple pencil sketches, elaborate ink drawings, color renderings, photographs, collages and photomontages. It is both useful for the artist who fills up the pages as a record of the development of one or various projects and for others to see the evolution, step by step.
