The Romanov Sisters
Fun Fact: This was taken in the Maple Room, Alexander Palace, with what looks to be OTM. Kaubach’s portraits are featured behind them, with it being (top left to bottom right) Tatiana, Olga, Maria, Anastasia. OTM’s portraits have been located, and one can find them on the internet, but Anastasia’s full portrait has never been found. I believe this was taken around 1908, pehaps 1909.
