Banksy vs. Bristol Museum

This Core77 posting takes a look at street/graffiti artist Banksy's new exhibit at the Bristol Museum in his hometown. The exhibit was planned in secrecy, and not even the museum's director met Banksy; instead, the artist worked on the exhibition anonymously amidst his large crew. Ironically, Banksy is famous for his (illegal) graffiti throughout Bristol, yet is now showing at a government-funded museum. His illegal behavior, then, has made him famous throughout Britain and the world.
It will be interesting to see what the public response to the exhibit is and how his work translates in a museum setting. His art is known for its political commentary, a fact that dovetails nicely with his usual forum of graffiti on the sides of buildings. Will this message be weakened if he instead shows his work in such a traditional setting?
