Whenever I see this photo, (the original snapshot is about 2" X 3") I think, yup, that's Curly. There's nothing written on the back, of course, so I'm not positive.
The fields behind him look like the Janson fields west of the farm yard, and that means this was 1947 or 48.
He was home from the war, where he'd been a mechanic. He was newly married and realized Dimey and Queenie, his team of horses, was being replaced by tractors, starting with this one. At least temporarily, he had good soil to work with before they moved to the sandy Mayhew Lake farm. He looks like he has the world by the tail, don't you think?
