Stefan Kostov was inspired by the graffiti pioneer – the Swiss painter Harald Naegeli, who started painting building walls in Zurich in September 1977. Naegeli was arrested in 1979, when he returned to the spot of one of his works to collect his forgotten glasses. Until then he had drawn about 900 graffiti in Zurich.

He was sentenced in absentia to 9 months in prison, and after serving his sentence he went to Germany, Dusseldorf, where he became a famous painter. Until now he had painted thousands of graffiti worldwide.

                                        Each of the multicolored works consists of 400 photographs of graffiti from Sofia City.
