English: “On 11 August 1916 (24 August 1916 in western world), Alexandra informed Nicholas that their daughters had spent all day posing for a new set of official photographs ‘for giving away to their committees.’ As it turned out these would be the last official pictures ever taken of the four sisters, by photographer Alexander Funk. Released from their usual all-purpose plain skirts and blouses the girls dressed in their best satin tea dresses with embroidered panels of roses, wearing their pearl necklaces and gold bracelets. Anastasia not having passed the socially liberating age of sixteen still had her long hair loose, but her three older sisters all had theirs specially marcel-waved and dressed in chignons, most probably by Alexandra’s hairdresser Delacroix.” — Helen Rappaport, Four Sisters

Pearls about their necks and bracelets on their wrists, the Tsar's daughters pose in evening gowns in one of the salons. The furniture is French. Family concerts would be held here. The organ behind the girls is stacked with well-thumbed sheet music. All the Tsar's daughters learnt to play the piano, with varying degrees of success. Tatiana was technically the best player. Both this and the following photograph come from Maria's album.

This official portrait of Grand Duchesses Olga, Tatiana, Maria, and Anastasia Nikolaevna of Russia dates to 1915 or 1916. It is from Livadia.org It was also featured on postcards during World War I and has been published numerous times in books and articles. Because of its age, I think it's probably in the public domain. If I'm wrong, please delete the photo immediately.
