Designed to provide a cinematic perspective drawing foundation and to assist those working on architectural drawings, concept art landscapes and interiors, cityscapes and interior design illustrations. In this sketchbook you will find 150 pages of 20 varied two point and three point perspective grids most of which open out across both A4 sheets to provide an extended drawing grid that is over 40cm (16 inches) wide. This wide format supports you to create truly dramatic views of this world and others.
