For Christmas, I received this copy of Recipes From the Tower Kitchen by Carol Haddix. It was produced by the Food Section & Test Kitchen of the Detroit Free Press. According to the introduction (written, I am guessing, in the 1970s), "the Tower Kitchen has been remodeled in contemporary orange and black - designed for efficient testing of each new food idea that appears in the Free Press Food Guide."
Most newspaper food section published recipe booklets and pamphlets, as well as their own cookbooks.
Carol, who went on to be the food editor of the Chicago Tribune, was very kind of answer my questions for my book, The Food Section.
