I have no idea what the original photograph was taken on. It is highly likely to have been the old box camera belonging to the family. It might have been some sort of brownie camera. I had to do a bit of photo restoration to really make the picture show up. This was my mother coming out of a teepee. Note the wild flowered pants. As I recollect those were all the rage at the time. Memories of days gone by. I have been getting some old photos and doing restoration as of late. All photo restoration work done on the iPhone.
