Street art began as art created in public spaces and has evolved over time. It originated from cave paintings and graffiti tags, and became prominent in New York City in the late 1800s. Street art allows self-expression and comes in many forms from political messages to cartoon-like doodles. It has faced criticism for being illegal vandalism, though some see it as a form of art. Notable street artists include Jon Burgerman, known for vibrant cartoon-like doodles; Keith Haring, who used lines to create contained works; and JR, who pastes large black and white portraits in public spaces.
