Hi

, this is my first post. Several years ago, when my great grandfather was going into a nursing home, my grandmother and I were cleaning out the house. I came across an envelope with 42 very old black and white negatives. They measure about 2x3"??? They were misplaced and rediscovered this weekend. I have NO IDEA how old they are but my grandmother's wedding photos are in there. They are in OK condition and I am wondering the best way to store these. It's probably been discussed here before but I haven't been through the archives yet.
Any help would be greatly appreciated.
Thank you.
