Photo of David Crocket Graham in Ya'an xeroxed from archive/diary box at Smithsonian. A handwritten caption (perhaps his own) on the back of the photo reads, "Not a brigand, but D C Graham at Yachow at the end of a collecting trip to Tatsienlu in 1923. #31. Tatsienlu is an old name for Dartsedo/Kangding while Yachow would refer to Ya'an.
