Two questions.
1) A. V's album labeled this one as "Tsarevich with cadets in Military School, 1915" (Peterhof, I think):

But I think it is incorrect. I think that one is only retouched of this one, which shows Aleksei with friend- cadets, Zehnya Makarov, and Vasya Agayev, with Grand Duchesses Olga and Tatiana, during sailings on the Dnieper River, in 1916 ) I think Grabbe's book says same:

So, what do you think, what is correct -- At Military School in 1915, or near Mogilev in 1916?
2) Date of this Aleksei's photo? 1905 or 1906?

Thanks in advance!
