Berlin Wall artists sue city in copyright controversy; Guardian, 5/3/11

Helen Pidd, Guardian; Berlin Wall artists sue city in copyright controversy:

"The East Side Gallery is one of Berlin's most popular tourist attractions, a 1.3km-long brightly painted stretch of the wall which divided east and west for almost 30 years.

But now the outdoor exhibition space is embroiled in an expensive copyright controversy after Berlin council destroyed some artworks painted on the wall and reproduced others without the permission of the original artists."
