I encountered Dread Scott’s curious flag project, “Flags Are Very Popular These Days” (2011), on Facebook and was fascinated by its simplicity. Last month, the artist placed the flags of four nations (Afghanistan, Iran, Iraq and Pakistan) on overpasses in upstate New York. These symbols of pride for four Muslim-majority countries— two of which America is currently (and officially) at war with — must have felt jarring to passersby who may not have been able to recognize their meaning or discerned their origins.
