The article deals with street art, which the author considers to be the freest domain of artistic creativity. A graffiti artist asks no one for permission, he does what he wants, where he wants, and when he wants. But this freedom offends those who are afraid of any form of uncontrolled expression. Street art is powerful - it is visible, widely discussed, it reaches everyone, and so it is an object of struggle. In the context of thus defined street art Gizycki writes about two famous artists of this genre: the contemporary cult figure - Shepard Fairey and Italian artist called Blu. Some of their work was overtaken by various institutional discourses. Occasionally the work was a cause of a scandal, but was also used for various advertising, corporation and political aims. In conclusion, the author asks whether and to what degree is Polish street art involved in similar discourses.
