Date: The seller dates this to c.1867. The back of the card gives the photographer's name as Hung Cheong Shing, and their address as "Opposite Messrs. Lane, Crawford & Co's, No 32, Queen's Road Third Story". HOPIC lists the photographer at this address from 1879-1881 (see https://gwulo.com/node/31857), so the photo may have been taken c.1880.
