Children of the artist. Olga and Anton Serov. 1906 Valentin Serov (1865-1911)

The picture has something of this: people, two, man, engraving, wear, sepia pigment, group, woodcut, woman, administration, chalk out, visuals, weapon, vintage.
Perhaps it’s a black and white drawing of a woman sitting next to a child in a field with a tree in the background and a sky.
