Going a long way towards solving the conundrum of exactly where street art, here also named as post graffiti, is positioned in relation to graffiti, fine art and commerce, Julia Reinecke's four year project took her out into the streets of Berlin, Hamburg, London, São Paulo, New York and other cities of the world, where she was able to research activists such as Banksy, Shepard Fairey, Jeroen Jongeleen (aka Influenza), Space Invader, Gomes, Solo One, Os Gemeos and D*Face. This book also considers commonalities between post graffiti and land art, pop art, Dada and Situationism and how post graffiti is used today in guerrilla marketing and image advertising.
