On the photo is Ivanovka estate, located in Uvarovsky district, Tambov region, Russia. It was the summer residence of the Russian composer Sergei Rachmaninoff in the period between 1890 and 1917 (until his emigration). It was the family home of his aristocratic relatives, the Satins, who were borzoi breeders (borzjatnik), their dogs were exhibited on the dog show in Tambov in 1891 and later (1914) and received medals. I think on the photo the Satin’s borzois. It is written that in the photo on the saddle the stableman Yakov (Andrus Kozlov)
