Muralists are getting some well-deserved buzz in Charleston right now, but what about the unsung heroes of chalk art? Local (chalk) artist Tim Edgar is not only a wiz at beatific lettering, but he also illustrates pictures that are inconceivably drawn using chalk. Those retro cars and mopeds on the chalkboard at Al di La? That there is just one example of what Edgar can do. Go there or to Early Bird Diner now to see his handiwork on display and prepare to be amazed.
