"I love old photos," photographer Irina Werning writes. "As soon as I step into someone else's house, I start sniffing for them." Last year, Werning asked friends and family to "re-enact" old photos of themselves for an ongoing project, which she christened "Back to the Future." This is Pancho, in 1983 and again in 2010, in Buenos Aires. (Werning's collection is reminiscent of fellow photographer Ze Frank's Young Me Now Me project—which, like Back to the Future, shot to the top of Reddit—but with even more exacting production values.)
