Probably the best quality image of this guy I've been able to upload. I'm not sure if that larger medal he's wearing is a Mengjiang or Japanese honor. Perhaps someone can identify it?

Demchugdongrub, unknown date and location.

Mongol Prince

An interesting photo (which, yes, I did first come across on wikipeida, though later sited through other sources) showing an extract from a Japanese handbook. This small book was meant to show to Japanese troops (mainly officers) who some of the key players were in the Chinese theater of the war, and how close a friend they were to Japan.
Pictured here is Altanochir, a Mongolian politician who served in the pro-Japanese Mengjiang government of Inner Mongolia under Prince Demchugdongrub. 

This is an Ally

A group photo of Japanese and Mengjiang officials, believed to be taken in 1937.
Prince Demchugdongrub can be seen in the front row, third from the right.
