Banksy is the name of an anonymous artist based out of London that is mainly considered a Graffiti artist, however, creates various forms of art around the world. Banksy tests the culture norms and challenges the realm of art. His work tends to have strong political influence and being anonymous can express ultimate opinions which are generally very offensive. His works are so popular and have generated a lot of talk and attraction, that many celebrities have purchased his works such as Brad Pitt and Angelina Jolie. I like how bold and cleaver his pieces and placements are, having a lot of thought related to each piece making the view think deeply of meaning and challenge their own perceptions on the matter.
