Really out of date film

These plates have been developed successfully when over 100 years old. Hope for my system yet.

I think that these are the same as have been covered in other threads, and were actually already-processed film negatives. I believe that the "modern" processing was separating and restoring them....but still remarkable. (I don't think a digital camera card would survive 100 years, and, even if it did, probably no-one would know what it was or what to do with it. )
