They were just cars in accidents, and that the photo's survived. Looking for old pictures you run across certain sites, like I search for Buffalo related pictures and fiind a treasure trove. Especially cars built in Buffalo like the Babcock, Pierce Arrow, Thomas, Atterbury, etc........ Also the Rochester Kodak Museum Archives is another. almost any town has an historical society, or museum. Search the areas you are familiar with, and dig deeper. Isn't the internet fun!
