Mandie, thank you, it was new to me, amazing. Stavka, 1916, of course. I don't know who would be the gentlemen. I thought of Count Tatishchev, but surely I am wrong. Laura, larri and Clock, thank you as well, some were new to me.
Well, I think that these are nice, full credit goes to the site written on the images. (I haven't been here for a long time, so most likely that these have already been posted).
