Here is what I believe to be a complete set of the Betty Crocker Recipe Card Library. Recipes are divided into categories and separated by larger category cards bearing the description of that group. The cards are dated 1971. The box is in excellent condition with some minor scuffing. The cards appear to be unused. The box measures 9" long, 6" wide, and 6" tall. The collection weighs 6 1/2 pounds! You will never again be without a good idea for a dinner or gathering!
