Tony, this is something I will suggest to my wifes family about my late father in-laws photographs from the African and Russian fronts.
He was a photographer for the German army. One day, out of the blue, he asked me if I would be interested in seeing some historical pictures. He then pulled out some shoeboxes and we went through about 500 contact pictures of some of the things he saw and recorded.
Absolutely riveting stuff. My wife didn't even know about these pictures, it was the first time he had ever shown these pictures or spoke about them, to her and her siblings.
Very nice present for your mother, I'm sure.
Mick.
