Main entrance to British Consulate compound, The Bund, Shanghai
University of Bristol - Historical Photographs of China reference number: St-s001. Sign by the gateway: NO THOROUGH-FARE. There appears to be a machine gun pointing towards the gate/camera, which along with the various types of military personnel guarding the gateway, suggest a time of unease/unrest - perhaps during the Boxer Uprising? See NA30-038 and NA30-040.
