I highly recommend you check out the book, A Literary Guide to Flannery O'Connor's Georgia by Sarah Gordon. It is available from the University of Georgia Press. The historic and contemporary photographs are brilliant. Whether you are a Flannery O'Connor fan or simply a fan of Georgia history this book is for you.
Full disclosure: I do not receive any compensation for the recommendation of this book. I just really like it.
