17. Some quick info...

"For framing old paperwork, the primary archival clear materials used are UV-filtering acrylic (Plexiglass) or specialty museum glass, which protect against light damage while being inert and acid-free. For direct, close-contact encapsulationpolyester film (such as Mylar or Melinex) is the standard for long-term, stable protection.".

This was from Lineco. A bookmarking supplies company (I've bought their stuff).

Also acid-free paper like 100% cotton rag, same for the backing, any mats, etc.

As an artist on rare occasion I've read about this stuff.

And, yes, away from any sunlight coming through windows I'd guess even with protective materials!
