Open Walls Baltimore is a street art project that began in 2012, took a hiatus last year, and now is back for May 2014. Curated by street artist Gaia, Open Walls Baltimore brings together world-renowned street artists to create an outdoor mural exhibition that brings life to the city’s streets. Participating artists include Maya Hayuk, Vhils, Swoon, Momo, the project’s curator Gaia, and many others. Head down to Baltimore to check out this great outdoor street art exhibit, and if you’re around on May 25, you can join the Final Friday celebration that wraps up the project.  Read on.
