Banksy is a pseudonymous England-based street artist, political activist, and film director. He has never publicly confirmed his identity. Active since the 1990s, his satirical street art and subversive epigrams combine dark humor with graffiti executed in a distinctive stenciling technique. 

Banksy uses a stencil technique to create bold, simple images that can be quickly sprayed onto walls. His style often uses strong contrasts (like black and white), clear shapes, and minimal details so the message is easy to understand at a glance. This allows his art to be both powerful and fast to create, often appearing unexpectedly in public places.
