All you need to know about graffiti is in this book” made by Benoit Ollive.

Graffiti is often misunderstood, and it is difficult for a graffiti writer to explain what he feels about it. Benoit has been asked by a book publisher to write a few pages to explain to teenagers how to practice graffiti. After hours and hours he came to the conclusion there was nothing to teach about it except providing the tool to do it.
