Picture Analysis

I posted a picture earlier this week. It's a family portrait and on the wall in the background there is another family portrait. I became greedy and really wanted that other family portrait, too. I coveted it. Desperately.

And then, a bit ago, I had an epiphany and did a side-by-side comparison of the only other family portait I have of ANY side of my family.

Here is the blow up of the picture in the picture:

And I'm pretty sure here is that picture.

Now to figure out what this is: Any clues? HELP ME!!!!

EDITTED TO ADD: This is a mourning lithograph. I wonder who they were mourning? I'm going to have to research that further.
