Mr. Brainwash created a huge 9/11 mural outside the downtown Century 21 store

Last year, we published this guide on the best places to find graffiti in NYC. And here's an unlikely addition to the list: The Century 21 department store located near the WTC site. The discount retailer commissioned street artist Mr. Brainwash (you might remember him from that Banksy movie) to create the piece as a tribute to 9/11, which consists of an American flag, a paint-splattered black heart and the phrase We Love New York. 

The mural will stay up for the next three weeks, so you'll have plenty of time to check it out.
