Nine graffiti artists who spray painted creations across the world-renowned 5Pointz building filed a lawsuit Friday in Brooklyn federal court, seeking unspecified damages from the owner who whitewashed away their artwork. [Snip] The aerosol artists say they are owed substantial cash damages because Wolkoff painted over their al fresco works. [Snip] The iconic buildings had more than 350 works of visual art on the walls — inside and out — when Wolkoff destroyed them, the lawsuit said. The colorful, eye-catching creations were torn down for good last summer.
