Hi, I have inherited two old school photos from about the 1930's. I think they can be from Chicago university classes, could be high school and more.Show a lot of persons, they are enlargements, seem to be taken at examinations. They are photographer's photos, only one has the photographer's name on it. I would like to know what classes these were and, for at least one of them, which years the photos were taken. I have tried to find out if there is anywhere on a Chicago university or library link where I could ask about this but haven't got very wise about it. Can anyone give me a piece of advice how to do? I really wish to know about these old fine photos.
