The back of this post card photo says, 'Gladys'.
Judging by the other 4 photos in the set, I'm guessing that this might be Nora & Gladys Nixon.
This is only one of five related photos.
I found this post card photo in an antique shop in Columbia Falls, Montana and am hoping to find the family it belongs to so that I may return it. Please don't hesitate to contact me, as I have no intention of asking for any payment. My goal is to avoid family memories being sold to 'strangers'.
