This tiny picture is only 3" x 3" and scanning enlarged it.
I glance at it and say, "They look so much like my mom and dad!"
Enlarging shows it is not them so I analyze and decide it is the fashion that makes me think it looks like them. Take the lady....dresses only for women way back in the 30's. (This looks like 30's or 40's to me.) My mother would only wear pants to go pick cotton or work in the fields. Dresses were usually hand made with the style you see here.
Then look at the man. Overalls with lots of pockets and definitely old and worn. (Just as the kids like today in their jeans with a worn-out look.) Cocked hat and an arm around his lady friend. The house is worn in appearance but livable with a probable out door toilet and water from a dug well. Electricity? I'd bet there was none.
But they look happy. That is the most important thing!!
