When art clashes with IP law: Banksy’s ‘Flower Thrower’

The works of UK street artist Banksy are critically acclaimed and highly valued. Banksy’s artwork would qualify for copyright protection, but Banksy’s anonymity is his hallmark. To enforce copyright, and therefore stop people copying his art, it would be necessary for Banksy to reveal his identity in order to prove his authorship (and therefore ownership) in any copyright.
