One has to ask what makes a photograph rare, that it has not been published in an English language book? With the assistance of Margarita Markova, I am posting below a few OTMA photographs, from Russian language books, that may not have been seen on this forum.
A group photograph taken in 1897 at Peterhof park, from left to right, Empress Aleksandra Feodorovna, King Christian IX of Denmark, the Dowager Empress Maria Feodorovna, Emperor Nikolas II and Grand Duchess Olga Nikolaievna.
Group photograph taken in 1902, from left to right, Imperial Court coachman, two governesses, the infant Grand Duchess Anastasia Nikolaievna, Grand Duchess Maria Nikolaievna, Grand Duchess Olga Nikolaievna and Grand Duchess Tatiana Nikolaievna.
Grand Duchess Olga Nikolaievna and Grand Duchess Tatiana Nikolaievna in the window of a carriage of the Imperial Train. Taken at Skernevitsy on 11 September 1903.
A group photograph taken at the main entrance of the Great Catherine Palace, Tsarsko Selo in 1911. At center is Emperor Nikolas II with his daughters Olga Nikolaievna and Tatiana Nikolaievna, surrounded by officers from His Imperial Majesty's Own Escort.
If these photographs have not appeared on this forum before please inform me so I can post more of this type.
