Partial 1967 encyclopedia set (Ann Arbor Northwest Side)

Found these around town in a number of little free libraries. Enjoyed them, and hoping to pass them on! Maybe someone even has some of the other books in this series. A really interesting snapshot of text and illustrated history of the United States. Includes books 3, 4 , 9, 10, 11, 12, 14, and 15. Easy contactless porch pick-up.
