Mazola Recipes Introducing the Pure Oil from Corn for Salads, Deep Frying and Shortening - this very old booklet is undated, late 1920s to early 1930s is my best guess-timate. It measures 4.5 x 5.5", and contains 24 pages, 64 recipes in all. Minor oil stains, still very legible and intact. Both the front and back covrs are shown in the photo.
