Sly Artistic City (2010)

Some argue that modern graffiti was born in Philadelphia, where the pioneers of wall-writing became citywide celebrities during the late 1960s and early 1970s. Graffiti eventually consumed the city, and a new mayor made it his top priority to fight back. In the process, the city's Mural Arts Program was born. Philadelphia is now a great outdoor museum. Yet graffiti still thrives, with new writers always ready to replace those who are caught or quit.

Unfortunately the movie Sly Artistic City is not yet available on HBO Max.
