Photographer Alex MacNaughton continues to traverse London's streets looking for the best graffiti. His first collection of photographs was eagerly snatched up by street art enthusiasts last year. Now featuring 150 new images all taken in 2007, his latest book is full of colour and life. Political, funny, angry or just plain weird, in stencil or spray paint, the images here present a London simmering with artistic passion. The book opens with a map of MacNaughton's travels around the capital's less salubrious parts, detailing his quest for the perfect piece of street art. Following are page after page of professional photographs, bearing witness to the skill and talent possessed by the artists. This great-looking, affordable volume provides a lasting record of this most fleeting of art forms.
