Do you have photographs from the early days of color photography? Have you scanned them and preserved them?
The colors do fade–so don’t wait if there are images you have not made from these photographs.
Digitize them (scan or take pictures) even if you do not know who is in the picture. These items deteriorate relatively quickly and your copy may be the only one.
I hesitate to call this an “old” picture simply because I am in it <grin>.
