Banksy does it again.

Banksy is an anonymous England-based street artist, vandal, political activist, and film director. His satirical street art and subversive epigrams combine dark humour with graffiti executed in a  distinctive stenciling technique. His works of political and social commentary have been featured on streets, walls, and bridges of cities throughout the world and are now valued by collectors. . Here one of his rare sketches, Girl with a Balloon, was actioned at Sothbey's for 1 mil plus.  Just as the hammer went down someone activated a shredder Banksy had hidden in the frame destroying the work.
