Bogdanov-Belsky, Nikolai Petrovich (1868-1945) Peasant children

The artist's signature in black pencil in the pre-revolutionary spelling "NBogdanov-Belskiy" is on the bottom left. Below is erased inscription in pencil "T. Voinich". On the reverse side is the inscription in brown ink "Today, December 8, 1943, the 75th artist N. P. Bogdanov-Belsky".
Slight dirt, tears along the edge, two left corners of the leaf are torn, with scuffs and stains on the back. The drawing itself is not affected. Perhaps the
work belonged to Tatjana Vojnicz, daughter of the Latvian doctor D.E. Vojnicz
(1893-1981), or it is depicted in the picture.
