I don't know why but when I see this it reminds me of all those photos of the Kennedy brothers. Perhaps same time frame and a bunch of boys ;)
Anyway, they are (left to right) Melvin Manning, Carl Manning (daddy), Raymond Manning, and Johnny Manning. All born in Lawrence County Arkansas. Melvin was a school teacher and then later an administrator. My Dad worked in parts most of his life (mostly agri but also Buick for a few years) and was once a soda jerk! Uncle Raymond was a farmer, and Uncle John was a business man and mostly notably, to me, one of those businesses was a beauty school in Kankakee, IL. He is the dad of my cousin Diane who supplied this great photo. Thank you Di!
