Publish date of ';The Detroit Times Cook Book of Vivette Recipes';?

The recipe pages are in a red tin, book-style box with 3-ring binder. Vivette was formerly housekeeper for the Edsel Fords and her recipes appeared every day in the Detroit Times - according to the title page. I am very interested in learning the age of this book and the sale price - have never seen one like it before.Publish date of ';The Detroit Times Cook Book of Vivette Recipes';?
It looks like it is from 1930. I found one that was sold on Ebay, to give you an idea of the price
