Gr 7 Up-This in-depth volume supplies readers with a lion's share of knowledge on the often-marginalized art form of graffiti. Ganter supplies a brief background of the art form, from its historical presence in ancient Pompeii through the modern-day hip-hop movement. After defining specific graffiti terminology, Ganter examines different methods and styles. The art descriptions are nicely supplemented with clear instructions along with visual examples. Ganter notably addresses the issue of legality by outlining the parameters of where readers can practice this art form without breaking any laws. The author uses general sketches in red and black ink for the first half of the book to portray the various graffiti designs. The latter portion relies upon full-on color to illustrate the different spraying styles. The book is at times somewhat technical, so those looking for a full art history of graffiti might wish to go elsewhere. Sample exercises for teachers to use in the classroom are also included. Consider purchasing for middle school and high school art classes, particularly in urban areas. Keith Klang, Port Washington Public Library, NY
