I could not find the negatives for this particular set of photos. It finally clued in when I read what was written on the back of the photo:
It is written in French and gives the name as simply Miss Vaudry and her address. It instructs to separate my Uncle and place him in a Vignette. The costs of the photos are listed as $3.00 and $15.00. I wish it also had the photograph shop name. My Great Aunt Laurette must have taken the photo as she was included in some of the shots. Mystery solved! I am so lucky to have such a precious photo!
