District Comics is billed as “an unconventional history of Washington, D.C.” The graphic anthology is unconventional, definitely, but above all, it’s ambitious. Editor Matt Dembicki, a local cartoonist, gathered an all-star team of artists and writers to peer into the District’s past, illustrating obscure chapters of our history, like the story of James Hampton, the janitor and outsider artist who built a religious shrine out of garbage in his Shaw garage. Some examine the individuals that make up history’s much bigger picture, like Rebecca Goldfield and Paul W. Zdepski’s “Taps,” the tale of the trumpeter who played at John F. Kennedy’s funeral. Others, like Grant Jeffrey Barrus and Jacob Warrenfeltz’s “Rolling Thunder,” pack an emotional kick. Most admirably, though, Dembicki’s collection doesn’t attempt to tell the whole story of the city—it’s too large to contain. But one thing is for sure: You won’t hear this stuff on any tour bus.
