Is There A Sculptural Equivalent of Graffiti?

At least once a week I take a walk across the Pulaski Bridge from Long Island City to Greenpoint.

This tree hadn't dropped any leaves yet. I liked the contrast.

Instead of turning left near the Brooklyn Ice Cream Factory like I usually do, I took a right.

These sculptures took me by surprise. 

A couple days later, I noticed I could spot this guy from the other side of the water.  Doesn't he look powerful from this angle?  Kinda like the King of the 99% with his nemesis in the background.

The Long Island Railroad tracks and the Midtown Tunnel are just behind this view.

Industrial decay is an urban look.

This building was built to last even if the smokestack is a little rusty.
