There seems to be some confusion over this photo. One site states it was taken in the city of Tienjin, China in 1911 by a Japanese journalist. Source. Another site says it was taken in Tiensten, Hopeh Province, China in 1942 . Source. I recently received this information from Alain Stauffer, Geneva : Chinese ufologist Shi Bo: "La Chine et les extraterrestres" (in French, since Shi Bo lives in Paris). He states in his book (my translation): "In 1942, an American man on duty was walking in the street of a town [not specified] in the north of China. He suddenly saw a black hat silently flying above the street. He immediately grabed his camera and took this first picture of a UFO in China. This American citizen wished to visit China very soon in order to trace the witnesses of this event."
