This is a large matted photograph from 1912. It is titled "I.O.O.F. Convention Williston, N.D. Pasonvault Foto" (At least that is how I am reading "Pasonvault" it may or may not be what is written). It is wonderfully clear and shows very nicely the dirt street and the Gates Buggy Co. Building.
The gents are all lined up in front.
The matting is deteriorated in places, there are dark spots on the back, there is some paper loss at the corners, edge wear, and there is a white spot and streak, all of which I have tried to show clearly in the photos and scan.
