A cabinet card from approximately 1904 when my great-grandfather Harry Koenig was a German naval surgeon in Tsingtau, China. The photo is pasted onto the card, instead of laminated onto it. I asked a neighbor and China expert, Professor Richard Belsky of Hunter College, where he thought it was. Rick replied:
"Very interesting. I think your photo must be of Jinan, the provincial capital of Shandong. Tsingdao itself didn't have a wall, and the walls in the picture are very impressive city walls, such as one would expect from a major administrative center like a provincial capital. The wall doesn't exist anymore, most city walls in China were torn down in the years since unfortunately. It is hard to tell but it seems that the photo shows the area in the foreground flooding, and I know the Jinan moat did flood at times. German influence was great in Jinan, there was a German concession there, and the Germans built a railroad from Tsingtao to Jinan (completed in 1904), so it makes sense that your great-grandfather would have spent time been there."
"Here are some photos of Jinan for comparison. The first two are different shots of the Jinan wall - note the water in the foreground of the first one."
