Rick, Rick Rick! In my collection I primarily focus on "paper" related items. When I saw those ORIGINAL Fred Gibb photos all curling up, being held down by distributors and that I cringed. You NEEED to get some rigid mylar sleeves for those photos. First, it makes them flat, then it protects the photos by being acid free and hard to protect them from being damaged. Here is a link to a supplier I use for my archival supplies. 25 rigid mylar sleeves are only $14.95! They have larger and smaller ones as well, I linked 8 1/2" X 11" for you. Don't wait, order them now! Temp change and especially humidity does a number on old photographs!
