Spray-painted subway cars, tagged bridges, mural-covered walls – graffiti pops up boldly throughout our cities. And it turns out: it’s nothing new. Graffiti has been around for thousands of years. And across that span of time, it’s raised the same questions we debate now: Is it art? Is it vandalism? Kelly Wall describes the history of graffiti.
