In the greatest city in the world art just happens :) New York's MTA - Metropolitan Transportation Agency which is in charge of the subway is making art too. Currently the MTA is under a lot of pressure and this took place at the Columbus Circle subway station around 11pm. The workers probably thought I am photographing them to complain. Nothing of that sort.
