Location: New York

This tribute to Martha Cooper for her 70th birthday was organized by How and Nosm. I can't think of anyone more deserving of such a birthday gift than Martha Cooper. This generation-spanning set of legendary street artists and graffiti writers went all out to pay tribute to one of the most important people in the history of graffiti. The mural only lasted a few days, but for me it's one of the murals this year.
