The Altoona Mirror newspaper has a number (probably more than 100) of historical photos of the Altoona area, Pennsylvania Railroad, etc. from the early to mid-1900s on flat metal lithographic plates. Is there a way of getting prints or digital scans of the plates so we can put them in a usable format? Unfortunately, they kept the plates but not the photo prints they were made from. Any advice or suggestions would be appreciated. At this point, I’m not aware of any companies that can make the prints.
