This cookbook was most likely published in 1979. I am dating that from the copyright information on the title page, which states: Copyright 1968-1979. The back of the book also contains 3 calendars, beginning with 1979.
The cookbook, over 30 years old, is in good condition but does show its age. There is some age discoloration to the inside covers, some cover wear including edgewear, scuffing, and creasing. In addition, there is a newspaper recipe that was inserted between 2 pages; those pages are discolored from newspaper - please see images. The insert is a 1982 newspaper recipe. I saw one neatly penciled recipe notation, other than that, the pages are clean.
