What makes this 1956 hardcover special is the dustjacket has survived intact, although quite worn, making it rare and the jacket has a very cool art-deco type design, showing a geometric design on pastelish green and black cover. Jacket rates fair with heavy edge wear all the way around book itself rates very good. This is 1956 hardcover of book from 1954. Part of Teh Addison Wesley course series in math, all of which are depicted on the back of the jacket.
