As a huge fan of the Impact series of How To art books I wanted to get to know the artform that made Banksy a household name. What was staggering was the detail to which Scape Martinez went into for the whole thing taking the reader from beginning concept to colours, from effects to the finished product explaining everything including techniques used by various artists in great detail along with a huge selection of photo's to back his POV. Its gripping, its compelling and you'll want to tackle a project of your own, however, one thing I will advise, is to make sure its your own wall or get permission from your local council, who if they refuse permission, will generally know of an ongoing project within your area where you'll be allowed to practice street art legally.
