it was the native americans old house
I don't think anything will melt, but the photos will most likely become damaged if exposed to the extreme heat that develop in an atticAt the floor of an attic it can easily become 120-130 degreesExposure to that kind of heat for any extended period of time is bad for collectiblesMy suggestion would be to put them in a closet within the house itself.
Being of Mixed Native origin, a PIT house; DUG IN dwelling would obviously be most effective in arrid climatesIt makes little sense to have a below ground level dwelling in an area where the water table might be high, or become part of a floating floor under bedding Various other mediums were used as wellIE: Mud/straw brick/ willow type trees/ hides/ etcfor the structure of the dwellingSome ingenious Native even surmised and fabricated double roofingHides or whatever was available as the main roof; then above that at some space was a second roof allowing air circulation, while maintaining the integrity of the main roof A more efficient albeit Ancient type dwelling would be dug into the side of a hill becoming a virtual cave.or a real cave No ancient dwelling was strictly energy efficient however, unless one was an EskimoIgloos are quite warm relatively speaking, and one can have a small pit fireCaribou makes an excellent blanket since it's hair fibers are hollow There is a resurgence of ancient/ other century type building such as log cabin/Cob homes/Cross cut timeber homes using CHINKING/ etcetc; which are far more viableOne can still have a dug in dirt cellarSteven Wolf
Dont chance it they will shrink and crack in timeNo way around it I suggests laying them under a bedroom bed
