The Cooper Union-owned wall in Cooper Sq. at Sixth St. and Third Ave., formerly home to the “Forever Tall” 9/11 mural, continues to be pelted with paint bombs. Two paint splots that appeared shortly after the mural was obliterated in September were quickly painted over, and the school filed charges with the police for the vandalism. However for several weeks now, Cooper Union hasn’t painted over the latest bunch of blobs, which include one each in red, white and blue and which neighbors are now saying look “pretty artistic.” Asked for comment, Claire McCarthy, Cooper’s spokesperson, said, “I just don’t think this is a story. I think we’ve said all we want to say about the mural.”
