Important: the girls are not being killed. All are being hung as a punishment and will survive.
I find the concept of a mass punishment, like a mass hanging of four girls here, especially compelling. I am unsure why.
Far left: despite the humiliating uniform, which exposes her crotch as well as those little holes for her nipples, this girl is trying to maintain her dignity as she hangs in straps. She won't succeed. Her crime: lesbianism.
Center left: this girl's modesty is, conversely, being assured by the heavy covering. I so love the arbitrary contrasts that one girl's exposure with the other's protection implies. Her arms and ankles are held strapped to a square frame behind her back, which also encases her feet. She can barely move.
Center right: this one is hanging voluntarily, to discharge a small debt.
Far right: another "morality criminal", shitting herself as she kicks. Often, jailers ensure girls are well fed and unrelieved before public hanging, so that their defecation humiliates them further.
This was a quickly drawn sketch. Not one of my best. My favorite is the girl on the far left.
