What would you call spray paint on a viaduct wall or on any wall? Under Lake Shore Drive and near the Navy Pier, the viaduct has been taken over with an artistic display of graffiti-like art. The mural was created by Gajin Fujita a Japanese American artist native of Los Angeles. A great display of graffiti, Asian motif, & local sports. The murals are part of Chicago’s 2012 BigArt free public celebration of outdoor arts.
