Olgasha, it seems that we have found the answer about the 'date enigma' of the Nicholas'photo taken at Hunting lodge in Poland. I guess the last one was taken at the same day as one you had previously posted some days ago. It is written, do notice, on the top of the photo ' September 19th '95'. I guess that the year is 1895, and the month matches as well, given the fact that the Imperial Family used to have spent their vacations at Spala in Autumn of a year.
Post scriptum:
Little Nicky with parents and Georgy
This one is new to me ! Thank you!
New of Nicholas (at least in cabinet card format)
Wasn't this one taken in 1913, or in 1914?
