WELCOME,HISTORY OF STYLE DEFINITION It's not easy to discriminate and define all the writer's styles as graffiti continues to develop all over the world. The time when a given style was brought to life (or when it was dramatically transformed) as well as the shape and the degree of complexity of letters can serve as criteria for difference of styles. The aim of the hierarchy, which is developed in this way is not to evaluate the style but only to describe it and set the borders between its versions kinds. That is why you don't have to agree with it, on the contrary it can be a reason for discussing the development of graffiti and its aims.
