New Yorkers and tourists were surprised to find a granite gorilla statue installed on Sixth Avenue this week outside of the McGraw Hill building. The statue was created by none other than Jeff Koons and is slated to go to auction with other at Christie's soon as a part of their "Post War and Contemporary Evening Sale". The eight-foot-tall piece is estimated to rake in $4-6 million dollars, so you better go take your picture with it now while you can. DNAInfo spoke with security at the site and found that they were not at all worried about theft because the sculpture weighs nearly three tons: "Who's going to take it? The main thing is to make sure no one messes with it." Koons has had his art installed outdoors in the past and as far as we know there have not been any incidents. The auction is scheduled for November 12.
