Almost four decades before the National Portrait Gallery opened its doors in 1962, Time magazine was already doing much of the museum’s job, capturing noted figures of the era in weekly portraits. The Smithsonian has collected nearly 2,000 of these original portraits since the late 1970s, and has been steadily rolling them out in a series of rotating exhibitions. The latest is “Time Covers the 1960s,” a collection of the decade’s most interesting front pages. Don’t be surprised if there are a few crossovers from last year’s Boris Chaliapin exhibit: It’s unlikely that Smithsonian historian and Time collection manager James Barber will be able to resist re-running some of “Mr. Time”’s iconic portraits. Regurgitation aside, the series captures a tumultuous and exciting moment in the world of art, too—colorful pop art by Roy Lichtenstein at his peak hangs near dark realist portraits by Henry Koerner and Robert Vickrey, whose masterworks have outlasted the critics who shunned them. The exhibition is on view daily 11:30 a.m. to 7 p.m. to Aug. 9 at the National Portrait Gallery, 8th and F streets NW. Free. (202) 633-8300. npg.si.edu.
