Banksy is the alias of a British street artist, painter, film director, and political activist. His true identity is unknown and has not been identified over the 20 years he's been active. His work, of mostly satirical pieces on politics, pop culture, morality and ethnicities, are a combination of graffiti writing and stencils. His work can be seen on streets, walls, bridges, and billboards of large cities. I believe he is worth recognising ecause he inspires change and challenges ideas. Much of his work influenced me to rethink social norms in a new perspective portrayed by his art. Also, because he chooses to remain unnamed, much of his work go unverified; but the idea and style behind his art is so unique that banksys' signature becomes the painting itself. I think that is something many artist aspire for- an identity.
