Os Gemeos - Painting Graffiti On The Greenway

Over the the last week of July a very public act of graffiti took place in Boston's financial district -- but it was not illegal. Os Gemeos, a pair of internationally known Brazilian street artists, had permission to paint a huge mural on the side of a ventilation building. It was part of their first solo museum show in the U.S. which opened on the first of August at the Institute of Contemporary Art.
