It was brought to my attention that what looked like flames coming from the windows looks like, with a change of perspective, an old sepia-toned photograph of children with their teacher in a classroom. On the left side of the window it looks somewhat like children sitting at their desks in an orderly row. While on the right side there appears to be two children, possibly girls, sitting on chairs in front of a desk looking back at what appears to possibly be a dark-haired teacher. The child on the left has blond hair while the child on the right has dark hair in a ponytail. The details of their legs as well as the chair legs can be seen.
From what I understand of the history of Hull House, it was an orphanage that also had classrooms for the children.
