By request - Borchert Field, Milwaukee - this photo is believed to be taken in the 1940's, while it never did host a MLB team it was the home of many professional baseball teams including the Milwaukee Chicks of the All-American Girls Baseball League, famed by the movie "A League of Their Own" starring Tom HanksThis picture, taken from the first base line, gives us a unique perspective of the ballpark.
We don't have any context for this photo, but we do know that it was a special day; the Brewers have put bunting up below the line of American flags along the Orchard's roof.
The opposing team's pitcher warms up in one of Borchert Field's foul-area bullpens:
I wish we could get a better look at that sign. It appears to read "REST ROOMS" but that's as much as I can make out.
Adding to the occasion, both teams are lined up along the basepaths, and a brass band stands waiting atop the pitcher's mound.
Notice also the massive light standards in front of the crowd. They were installed in 1935 as Borchert Field was updated to accommodate night games.
Behind home plate, we can see a large floral arrangement and photographers crouching to snap a picture.
With the band and flowers, this event bears a distinct resemblance to this photo, taken during a pre-game ceremony at the 1950 season opener.
It's not the same game—the visiting team's jackets don't match—but seems to be the same kind of ceremony. Odds are our mystery photo shows Opening Day at the Orchard. But which one?
