Thank you, moonlight tsarina, for posting this photo.
I've referred to it on several threads; it is also on prominent display in the traveling exhibit which began last year at Santa Fe, New Mexico.
You'll note Tatiana is having a nice big wink at the photographer--probably Anastasia--and is seemingly holding down poor Paul Voronov who, after all, is employed by the father of these rather bumptious girls! Rock and a hard place time for him, I think. Be my guest at interpreting what is going through Olga's mind. As for Marie, she looks a bit squashed into the arrangement. To my mind the photo has all the hallmarks of an impromptu tableau, brought about by Olga's mischievious sisters for her benefit and theirs.
