This was in a old Worth Point lot of 50 or so images and it was labeled as being "70s", but I would have said this was from 1968 as it looks like a red bill to the cap. Of course, it's Cecil Upshaw in the middle and I would swear it's Tony Cloninger on the left, making it early 1968. I just cannot hang an ID on the lefty: George Stone, Dick Kelley, Skip Guinn, maybe even Ted Davidson? Not a lot of lefty options around then.
Any help appreciated.
