"QUALITY" Baseball Flannel - 1950's King O'shea tagging

Out junking in Toronto and saw this jersey hung on a wall (back facing out) in a vintage clothing store - the pinstripes and "3" had me thinking of The Babe.

Tremendous shape for what I assume is a 1950's jersey? Needle in a haystack time - anyone recognize the team moniker? Thanks!
