Graffiti and street art are best viewed in their natural setting, in the city, on the streets. And because of their nature contextualization is not necessary. However, after many decades of research, documentation, and promotion of these art forms, it became obvious to us that if general viewer gets a little bit more information about the pieces or the authors, they will start to appreciate these art forms wholeheartedly. The consequence of this intervention is people who start enjoying their urban surroundings more and artists that get more understanding, appreciation, and creative opportunities. We wish to provide this missing link between the artists that produce their art in the streets and viewers in a reliable and scientifically correct way.
