Since 2006 artist Joe Mangrum has taken to the streets of New York, Chicago, San Francisco and elsewhere armed with sacks of colored sand that he sprinkles by the handful to create sprawling temporary paintings. Each work is spontaneous in its design and evolves as Mangrum works, spending upwards of 6-8 hours hunched over the ground to complete each piece. The artist estimates he’s completed nearly 550 paintings over the last few years. A graduate of the Art Institute of Chicago, his paintings have appeared at The Corcoran Gallery, the Museum of Arts and Design in NYC, as well as The Asia Society. He also made a recent appearance on Sesame Street. You can see works in progress over on Facebook, and limited edition prints are available through King Art Collective.
