Roast a Child!
That's funny! The woman tries to roast the child in the sun! The rays seem to be flames, the woman's face is concentrated and the posture is tense so it is easy to see she is heavily working. Anyway she doesn't seem to be a loving mother or caring nurse and the child is not happy if it is alive yet...
Don't think the poster's slogan is something like "kill public enemies' children" or "good boy is a roasted boy"! Actually it says "Week of the Child" (above) and "Children are flowers of a commune" (below) in Georgian (left) and Russian (right). So you see the artistic mission accomplished quite crappy! However this early Soviet poster was published in the Great Soviet Encyclopedia (1926). I can't decide why they chose it for the book. The Encyclopedia's editor was either an idiot or anti-Soviet joker or both.
