"Graffiti art is constantly changing. Fresh coats of paint and newly pasted posters appear overnight in cities across the world. New artists, ideas and tactics displace faded images in a perpetual process of renewal and metamorphosis. From Los Angeles to Barcelona, Stockholm to Tokyo, Melbourne to Milan, wall spaces are a breeding ground for graphic and typographic forms as artists unleash their daily creations." "Current graffiti art is reflective of the world around it. Using new materials and techniques, its innovators are creating an original language of forms and images infused with contemporary graphic design and illustration. Fluent in branding and graphic imagery, they have been replacing tags with more personal logos and shifting from typographic to iconographic forms of communication. Subverted signs, spontaneous drawings, powerful symbols are curious characters represent a worldwise outdoor gallery of free art." "Street Logos is a celebration of these developments in twenty-first-century graffiti, an essential sourcebook for all art and design professionals and a delight to everyone excited by the vitality of the street." --Book Jacket.
