The document discusses the history and origins of graffiti art. It traces graffiti back 30,000 years to prehistoric cave paintings. Modern graffiti emerged in the 1960s with teenagers tagging subway trains in New York City. Graffiti grew closely associated with hip hop culture in the 1980s as artists used spray paint and stencils to create designs. Artists like Basquiat were influential figures in both the graffiti and hip hop scenes in New York during that time. Graffiti continues to influence modern art movements while also dividing opinions as more mainstream artists like Banksy have adopted the style.
