This photo appears to have been taken of one of the exhibits at the Oregon State Fair in Salem, Oregon. It shows a pair of "high wheels" loaned by Baker County in eastern Oregon. Since the wheels had only a single tongue and thus would not have been used with a horse and buggy, or with covered wagons, presumably they were used with some type of farm equipment. The photo is from the Hugh Stryker Collection.
