An American Navy sailor poses beside an ornate cast-iron postbox on a tree-lined street, likely in the former German concession city of Tsingtao (Qingdao). Retaining much of its European colonial architecture, Tsingtao was a favored liberty port for the U.S. Asiatic Fleet during the interwar years and into the early 1940s, offering sailors picturesque backdrops for souvenir photographs.
