Ethnic groups in Russia. Sart Elizabeth Merkuryevna Boehm (Endaurova) (1843-1914)

The picture has something of this: people, lithograph, vintage, retro, portrait, man, paper, woman, antique, wear, engraving, collection, post, postcard.
Perhaps it’s a painting of a boy and a girl standing next to each other with a caption in a foreign language on the bottom right side of the picture.
