Book Description: Ever since anonymous spray-can art began appearing on city walls in New York and Philadelphia in the late 1960s, graffiti has been a ubiquitous presence in the urban landscape, its artists largely unsung heroes. As hip-hop culture spread from America, graffiti became a worldwide phenomenon, emerging in the 1980s as the symbolic artistic language of young people everywhere and one of the most potent influences on youth-oriented marketing and design. With more than 2,000 illustrations by over 150 artists from all over the world and interviews with many of them, this visually arresting book is the most comprehensive survey of graffiti art ever published.Today's young graffiti artists incorporate a variety of mediums-including stickers, stencils, oils, acrylics, and oil-based chalk-as well as an ever-expanding range of social commentary. This evolution in style and subject matter has earned graffiti the respect of the art world and guaranteed its long-lasting influence on art, graphic design, and style around the world. Great fun for graffiti and pop-culture buffs, the book is also an essential reference work for anyone involved in the visual arts today.
