Here is a scanned version of the photo that Pardus has seen. It was taken by my grandfather and the American in the picture was an Army buddy of his that he traveled with extensively across SE Asia while they were on leave from their duty in the PI. Even the poor image from the scanner shows clearly that the natives in the picture are Montagnards. The caption reads:
"Old tiger killed in woods near Moi native village of Klong Beuss, Cagne Plateau; 14 Kilometers northeast of Djiming, French Indo-China. November 8, 1928."
The species of tiger shown is, to my understanding, a subspecies indigenous to SE Asia that is currently endangered with only a few hundred left in the wild. I do not know where the places referenced in the caption are, and could not locate a map on line to indicate where this was. Also, I have no idea how my grandfather and his buddy got to this location as it must have been, at the time, way out in the middle of nowhere. As far as I can see even now most of the roads in Vietnam are close to the coast. It was not my grandfather's only trip to Indo-China, as I have home movies he took as late as 1936 or 1938 when everyone in the military knew it was just a matter of time before we would be at war with Japan.
If anyone has more information as to where this photo was taken, I would love to hear from you.
Also, when I can get a better image from a better scanner I will post it.
