I think he's correct about Cochrane.
In 1934, 5 and 6 Dykes was a player / manager for the White Sox, and Cochrane was player / manager for the Tigers.
I don't think Lombardi managed a major league team, and that catcher is about the right size for Cochrane, too thin to be Lombardi. Face looks like Cochrane.
I thought I had one of those, and found it in the first box I looked in (for once). When I saw the post I thought of the image that had Durocher arguing, but Leo wasn't managing back then so I knew I was thinking of the wrong image. Here's mine.
