You Have To Travel Deep Down Into The Underbelly Of NYC To See These Pieces Of Art

The Underbelly Project is New York City's best kept secret. 

This mysterious art project is on display in an unlikely place -- NYC's subway tunnels. More than 100 artists were let into the tunnels in 2009 to paint whatever they wanted. 

Not just anyone is allowed to walk into the tunnels to see the artwork. In an effort to keep people safe and preserve the art, those who are interested can get more information from The Underbelly Project's official website and newsletter.
