Here in Wisconsin, that stash would get all moldy and mildewed. I had a box of pictures against an outside wall of a closet with louvered doors. Next thing I knew they were all stinky. My daughter-in-law had boxes piled up against the walls for one winter. The walls were all black when she took them down. And this house has been newly resided, rewalled and very well insulated. I try to keep a little air circulating behind anything on the outside walls.
