Simple bombing with huge tags can hardly be considered art because it lacks artistic sense and purpose. Nevertheless, for the law any intrusion or damage into personal or public property without permission is illegal. While the culture of graffiti presupposes drawing secretly graffiti paradoxically remains both: a criminal act and a piece of art. However, a slow process of adaptation of this type of street art to the global cultural process is taking place with graffiti being exposed in museums and sold on auctions. The époque of technological progress gives people countless possibilities of self-expression: traditional forms of art remain accessible while a number of absolutely new ways, such as 3-D painting, comics, and animation, for example, appear day by day. Art is taking different forms in the era of postmodernism, and what was yesterday considered to be trash today is highly valued due to its originality and non-conformism. In the postmodern époque, the initial understanding of pieces of art as those depicting reality and conveying the serious message to the society has become irrelevant. We live in the age where the form is also a message, moreover, where the message is not compulsory that is why graffiti asa pure impulse of people from the poor districts of big cities is becoming interesting to the owners of the galleries. The museums of modern art in London and New York compete in exhibiting the strangest, the most unexpected pieces of art, and graffiti is gradually taking its place in the contemporary art world. Moreover, graffiti was anonymous earlier while now authors, painters become celebrated people and are called real artists. It is possible to recall the success of Banksy who became famous and started selling his works without even disclosing his identity. This fact proves that for real art the personality of the author is secondary compared to the power ofhis artistic expression.
