This one could be lightened up.
Here are a couple more from the Minnesota State Fair.
Considering the year, I think it's interesting that I can identify only one horse drawn vehicle in Herb's photo, the wagon right side center.
OT, but here is some info on Walter Christie and his front wheel drive race cars:
The photo is latter than 1907. Each auto has a license plate. The first MN plate state wide was 1909. The plates are the shape of the 1909 and 1910 plates. Also the second auto on the right is latter than 1907. More like a 1909 or 1910.
later - not latter.
Also the two autos facing us on the left look as if they are Model T Fords.
Also, the rear fenders on several autos are curved, which was not common at all in 1907. Several have curved front fenders, also not common in 1907.
The Minnesota State Fair in early years had an "Automobile Day".
Wow, it still looks like that today. That's for sure the same grandstand.
DEFINITELY NOT 1907.
That photo was taken no earlier than 1912 based the automobiles in the photo with their wide, light colored aluminum (later tin plated steel) 1912-13-14 Minnesota license plates with black digits.
I can see at least two Model T Fords (look at the closeup in the eBay listing).
The caption was added at a later date.
The photo is currently listed on eBay. Due the size of the photo, it may have been part of a museum or historic display. That's probably when the mis-dated caption was added.
Darel - you already know this. Minnesota registration started in 1903. Even if the photo were taken in 1907, the cars would still have pre-state license plates, typically the black leather plates with which you and I are familiar.
