That’s my mom, in the next-to-the-top row. She has reddish hair and no glasses. I don’t know the vintage of this photo, so I’ll guess it’s in the late 1970’s. This appears to be a high school reunion, because my mother didn’t belong to any clubs as an adult that I know of, and the picture is taken at the “new” Lenoir City High School.
I’m hoping the LilSis can help flesh out more details of this photo. There’s no writing of any kind on the back of the photo. Just another thing in my mother’s collection of stuff.
