How does this artwork elucidate its Auschwitz and Josef Mengele?
Josef Mengele was a physician who worked at Auschwitz, a concentration camp. His research subjects were better fed and housed than other prisoners and temporarily safe from the gas chambers. He established a kindergarten for children who were the subjects of experiments, along with all Romani children under the age of six. The facility provided better food and living conditions than other areas of the camp and even included a playground. When visiting his child subjects, he introduced himself as "Uncle Mengele" and offered them sweets. However, he was also personally responsible for the deaths of an unknown number of victims. Author Robert Jay Lifton describes Mengele as sadistic, lacking empathy, and extremely anti-Semitic, claiming that he believed that the Jews should be eliminated entirely as an inferior and dangerous race. Mengele's son Rolf said that his father showed no remorse for his wartime activities. A lack of regulations on his experiments allowed Mengele to perform his experiments freely.
A former Auschwitz prisoner doctor said:He was capable of being so kind to the children, to have them become fond of him, to bring them sugar, to think of small details in their daily lives, and to do things we would genuinely admire ... And then, next to that, ... the crematoria smoke, and these children, tomorrow or in a half-hour, he is going to send them there. Well, that is where the anomaly lay. 
Mengele had a fascination with twins. He was interested in the difference between identical and fraternal twins as well as how genetic diseases affected them and where they originated. The experiments also distinguished between genetic traits and those developed by the environment of the child. Mengele was known to pretend to be off duty while a train of new prisoners arrived so that he could personally select any twins whom he saw. He operated on children, partly to find genetic weaknesses in the makeup of Jewish or Romani people in order to provide scientific evidence for the ideas of the Nazi party. Mengele hypothesized that his subjects were particularly vulnerable to certain diseases because of their race. In addition to that, he believed that they had degenerative blood and tissue based on his samples.Mengele or one of his assistants subjected twins to weekly examinations and measurements of their physical attributes. He performed experiments such as unnecessary amputation of limbs; in another experiment, he intentionally infected a twin with typhus or another disease and transfused the blood of the infected twin into the other one. Many of his subjects died while undergoing these procedures. After an experiment was over, the twins were sometimes killed and their bodies dissected. Miklós Nyiszli, a prisoner at Auschwitz, recalled one occasion where Mengele personally killed fourteen twins in one night through a chloroform injection to the heart. If one twin died of disease, Mengele killed the other so that comparative reports could be prepared after their deaths.He was known for experimenting with eyes. One of his particular studies regarded heterochromia iridum, a condition where people's eyes are differently colored. After he killed heterochromatics, he removed their eyes and sent them to Berlin for study. Another of Mengele's experiments with eyes involved attempts to change eye color by injecting chemicals into the eyes of living subjects. His experiments on dwarfs and people with physical abnormalities included taking physical measurements, drawing blood, extracting healthy teeth, and treatment with unnecessary drugs and X-rays. Many of the victims were sent to the gas chambers after about two weeks, and their skeletons were sent to Berlin for further study. Mengele sought pregnant women, on whom he would perform experiments before sending them to gas chambers. Witness Vera Alexander described how he sewed two Romani twins together back-to-back in an attempt to create conjoined twins. The children died of gangrene after several days of suffering.
