I am looking into this for a friend of mine.
I have four pictures that I'm guessing are from the 1940s. I am wondering about the company "Knowles Bros" and what the men are transporting (bags say "Eagle" on them). I am also wondering why they are transporting them and where exactly. The images say Cascade, Idaho, which is what led me to this specific forum.
Any information relating these pictures is greatly appreciated!
