Interesting information Stu. Thanks for the education. I will go on faith what your friend is saying is correct. Kind of changes everything ive been told or read in the past. Also agree that Michaels is a great place to go. That is where I've always gone to buy a frame. I have yet to frame any paper or flags, preferring to keep them in the dark and the fact that real estate is not cheap.
But I still do think that the key to preservation as I noted is to keep any paper or cloth items OUT of direct or semi direct sunlight. This is the real killer and difficult to truly control IMHO. My war room has room darkening shades. So for the 99% of the time, the room is completely dark
