Art Whino gallery in National Harbor (Prince Georges County, MD) has the most amazing street art exhibit called heavy hitters, all the graffiti, shoes, and pop surrealistic art is from that exhibit. They even had one of the artists tag the wall for the show (that's me studying the illustrations). On the other side, an equally interesting exhibit, called Mortal Plush has plus sculptures all showing varying emotions. If you're in the DC area, stop by www.artwhino.com
