This is a rather grainy photo, but this view east looks like it was taken from the roof of the bank. I originally thought it was taken from the roof of the hotel. But the roof to the bottom right looks like the corner of the Hotel Menasha before the addition in 1916. (My thanks to David Mulvey for the correction.)
With what appears to be a vehicle in the center and with the unpaved street, I'd say it's pre-1910. And look how large St. Mary's looms in the distance.
