Prairie du Chien, Wisconsin, 1970s

Roger Wollstadt appears to have lived or visited just about everywhere in the United States, as we can see from his Flickrstream, and lucky for us he took quite a few photos that are perfect for our carspotting series in the process. One of those places was Prairie du Chien, where he took the above 1975 photo and the below 1970 photos. He even provided locations: South Beaumont Road, above, then Blackhawk Avenue, below, and the train station after that. What do you see here?
