Included are three volumes of Dell Publishing's American Heritage New Illustrated History of the United States: Volume 6 - The Frontier, Volume 7 - War With Mexico, and Volume 9 - Winning The West. These are vintage history books from 1963 and contain some very nice illustration work. They are in very good vintage condition, with the only defects being some scuffs on the spines of vol.'s 7 and 9, as well as a name written inside the front cover in vol.'s 6 and 7. Otherwise, these are in excellent condition with no writing or highlighting in the text or margins.
