Just picked this lot of 25 balls up and need to do the research, but love the game used look and obvious meaning they once had to the original owner
A few are stamped "Eastern League" and many have game results - including dated pitching results like, "no hitter", "one hitter" etc. Most are dated to 1954 and identify town teams that most prob played in minor leagues below the level of the eastern league at that time.
