Vintage recipe file 8 x 10 blue gray white not like momma's

This is a vintage recipe file. It is an accordion type file. Many separate files inside. Each one is stamped  with individual types of food.  the front says let's eat! It shows a granny lady with her long dress in her apron, slaving over the hot stove. I should say slaving over her monster of a are gray and blue, black, and gray. Shows somewhere on the edges. It is bound by two white strings. The size is 8 x 10.
