The theme of this series of illustrations is historical events, and several major historical events are expressed in an abstract and implicit style. My favorite is the last one, which is about the Holocaust (it can be the Holocaust suffered by the Jews or the Nanjing Massacre).

In movies and many historical records, parents hide their children in the closet to protect their safety. The illustration reflects the complex emotions of the child when he opens the door and finds blood on the ground and his parents are missing.
