With wall space at a premium in D.C. these days, you’re not going to see the entirety of a gallery’s holdings if you just walk through its storefront. The creative minds at Addison/Ripley Fine Art remedied that problem by creating a new show from the stuff in their storage unit, the artistic equivalent of rediscovering an outfit buried in the back of your closet. For this exhibition, the gallery has uncovered a colorful and sculptural piece by local treasure Sam Gilliam (pictured), a bold 1960s floral print by Alex Katz, and some recent images by D.C.-based photographer E. Brady Robinson. The works in the show don’t have much in common besides their gallery ownership; some were traded, some were gifted, and some were bought. The organizers hope to provide visitors with a history of the gallery and some insight into how collectors acquire and display art, while allowing guests to make connections and discoveries of their own. The exhibition is on view Tuesdays through Fridays 11 a.m. to 5:30 p.m., to Aug. 21, at Addison/Ripley Fine Art, 1670 Wisconsin Ave. NW. Free. (202) 338-5180. addisonripleyfineart.com.
