Many might find these photos sad. That's often what comes out of a black and white photo, by the way: nostalgia.
But above all, I find that these photos create an empathetic bond between the subject and us. Empathy that highlights our common humanity. I'm convinced that every person on Earth, whatever their origin, can have the same conclusion.
At the heart of nostalgia and/or sadness is empathy.
I love this selection of photos!
