Ethnic groups in Russia. Siberia under the snow. Elizabeth Merkuryevna Boehm (Endaurova) (1843-1914)

The picture has something of this: retro, vintage, people, portrait, post, lithograph, antique, paper, man, postcard, woman, postal, two.
Perhaps it’s a postcard with two children and a dog in front of a picture of a boy and a girl with a white.
