Banksy is an anonymous British street artist, political activist, and film director, active since the 1990s. His satirical street art and subversive epigrams combine dark humour with graffiti executed in a distinctive stenciling technique. His works of political and social commentary have been featured on streets, walls, and bridges throughout the world. Banksy's work grew out of the Bristol underground scene, which involved collaborations between artists and musicians. Banksy says that he was inspired by 3D, a graffiti artist and founding member of the musical group Massive Attack.

Banksy displays his art on publicly visible surfaces such as walls and self-built physical prop pieces. Banksy no longer sells photographs or reproductions of his street graffiti, but his public 'installations' are regularly resold, often even by removing the wall they were painted on.
