The surface of Howard Street will become a canvas for 3D chalk artists and local street artists at Chalk Howard Street, a festival devoted to art scrawled on pavement. Artists Anat Ronen and Nate Baranowski will reate murals that function as optical illusions, allowing guests to take photos with superheroes and characters that appear to be crawling out of the ground. The free one-day event in Rogers Park will also feature live music, entertainment, food and drinks, as well as plenty of opportunities to snap a mind-blowing shot for your Instagram feed.
