well! letīs start, I want to verify, with your help, this information!
I donīt know anything about baseball or stadiums (mainly because I donīt like), so my only help is the observation (and your invaluable help and knowledge).
Unfortunately we donīt have many pictures, so I'll use this one:

I look at those holes behind these people. And I have two names: Wrigley Field and Comiskey Park. This is my starting point. Interiors of these two football stadiums circa 1949.
An essential question before continuing wasting time. Are the two in Chicago? Remember, I donīt know anything, and can shock you which do such simple questions

then sorry...
I found holes at Wrigley Field... Click to view attachmentWhat a fool I've been, is for bats, right? LOL!!
... Track discarded. Let other tracks ...
I never doubt about a year: 1932... just kidding... 1949.
As I recall, Marilyn was in Chicago on two occasions: 1949 (LH tour) and 1958 (Promoting SLIH).
(Now come a hustler and tell us that she also stayed another year

With regard to place ...

Now, I want to find out who is who...

* 'Buddy' Rogers: Mary Pickfordīs husband and actor. I think and I hope this gentleman. I'm not very good physiognomist
* 'Forty Thousand' Murphy: Joe Murphy was an usher.
The nickname origin of usher Joe Murphy, though, was simple. Whenever he was asked to estimate Wrigley Field's attendance, he'd say "40,000." Thus, he became "Forty Thousand Murphy".
* Monroe: This I leave, imagine how many Monroe in this world ...
* 'Old Fiher' or Fimer (I donīt know): ?
well, now Iīm tired...
