TWO COUPLES?

I wish I knew anything at all about the four people in this cabinet card. Unfortunately, there is no identification whatsoever on the back. It’s a great outdoor portrait though, taken on what looks like a glacial rock, with a hill in the background. I love the casual interplay between the two on the left. The man on the right is nearly smiling. The card has some light marks and scuffing. Unfortunately, some of that is at the center. Still, a highly unusual image.
