Vintage Decorum Hardback Book Slip Cover 1979 A Practical Treatise on Etiquette. Book is vintage pre-owned. Please see all photos for visible condition. Says Christmas 1979. No noticeable markings/rips/tears but I did not turn each and every page - I flipped through the pages. It doesn't look used much. Published Westvaco Corporation. Collectible according to research. There is a hint of age smell to it but minor.
