As a novice I have handled maybe a few hundred vintage photos in all. That being said it seems quite obvious to this novice, due to emulsion (correct term?) and wear, when the paper was made that the negatives were printed on, and even an approximate period of the photo mfg date. I guess we sometimes forget common sense? Of course there could be old paper that made the photos from negatives today, but I can't believe the wear would look the same?
