Banksy's Self-Destructing Painting

Guest: Elizabeth Legge, Associate Professor of Modern and Contemporary Art, University of Toronto. Walking down a street in London or New York, you might see tourists snapping photos of a surreal stencil spray-painted on a public wall. The anonymous street artist Banksy’s work has become so sought-after, some of his pieces have sold for more than $1 million at auction. Did you hear about the Banksy original that self-destructed as soon as the bidding was finished a few weeks ago?
