Great idea to digitalize these old photos.
I aprove of your choice of not retouching them so that we can almost feel like we're holding them in our hands.
I am a great an of old photos, I love the faded shades and the different way in which people reacted when facing a camera... it was always a special moment and I bet no one would say, like we do these days, "Ah... I don't feel like having my picture taken" ;)
