Photo identification of park and teams: help needed ~1908

[baseballart]

Some time ago, I acquired three small photos. If anyone can identify the park and teams, that would be great. I have scanned the photos at 800 dpi and added the link to the very large photos on my flickr site

I suspect the ballpark is unique enough that it won't be too hard to identify for those with expertise in stadiums. Despite the writing on the back, the players in photo 3 don't look African American. September 7, 1908 was a Monday, so if Labor Day was indeed that day back then, at least that part of the identification is correct.
