A Little Help, Please . . . 1910 White Sox Park

[Yaw]

I've concluded this is a 1910 image of the White Sox Park in Chicago

My thinking is as follows . . .

1) The sender of the card states that the field is the new home of the White Sox as it look on Labor Day, 1910 (Park opened in July of 1910)

2) The scoreboard has a promo for "George W. Jackson Co.." Jackson was a friend of Comiskey who was contracted to build the park

3) The wooden bleachers were later replaced, but their presence make perfect sense for 1910

But there is a couple curiosities I cannot figure out . . .

1) Why is there a flag pole in left field and in fair territory? Have you ever seen an early image with this flag pole?

2) The scoreboard is set up to show the Cubs vs Brooklyn, yet the Cubs never played Brooklyn in 1910 on any date that was even close to Labor Day.

I'm confident that it is White Sox Park . . . but not convinced.

Can any one help me with definative facts, rather than random speculation (I have enough of my own - see above)

Thanks!
Dan
I'm sure it is White Sox Park . . . but I just can't figure out the flag pole mystery . . . any ideas?
