Flickr user Shaun Barrows made great use of the lines outside of National Geographic headquarters for this throwback to the 1970s image titled Interupted. We particularly like the way the anonymous man’s face is obstructed by the barriers.

Did you know that there are two photo exhibits currently on display at National Geographic Headquarters? Kodachrome Culture: The American Tourist in Europe, will be up until September 7, and Lions & Leopards, The Work of Dereck and Beverly Joubert will be there until October 4.
