Hello!
I've just searched on the Maria pages, and there isn't such a thread, so let's start it! I think there aren't a lot of pics of Mashka and her brother. Their relationship have been dicussed many times, but I'm sure we could all use some visual aid...
In Finland with their father, 1908.
With Anastasia, 1908.
With Anastasia and Tatiana, 1906 (let's say this one counts!)
Would anyone have some more? There doesn't seem to be a lot of photos of Alexei and Maria alone.
