FYI... The mosaic mural at City Tech has been saved! The college hired a firm to take the mural down in sections and crate it. Actually Joe Lhota, who is a CUNY trustee, and others, spoke on behalf of saving it at one of the board meetings.
Since 1% of the new building cost must be set aside for art, they're hoping it will be re-installed somewhere in the new building. They're still working on the details. But even if that doesn't work out, at least it wasn't destroyed.
