Outdoor and Underground "Art Galleries" in NYC

New York City is home to famous art collections like the ones at the MET and MoMA. But there’s something to be said about art that blends into the world around us. Here in New York City, art can be found pretty much around every corner, and even down the steepest set of stairs.  On this week's Cityscape, we’re exploring art scenes that live on our streets and in our underground -- from large murals that adorn the sides of buildings to mosaics that help to beautify the subway system.
