This is a Vintage Who’s Who Guide titled “National Social Directory” . Published yearly this one is from 1978. Basically it is a Hardcover book of the creme-de-la-creme of Society! Did your family make the List? You can find out here! 726 pages with addresses and phone numbers! Codes reveal affiliations and even a list of married and maiden names! Yikes! Hope these books didn’t fall into the wrong hands! No sure if they are still putting these out, I would guess if they are, it’s online only with encrypted password protection! This Book is in good condition with minimal wear and just some foxing to the page edges, fading and soiling. Please see photos for the best idea of condition.
