Borden's Advertising Calendar

I found this advertising calendar at a yard sale more than 10 years ago, but have not been able to find out anything about it. It is 20 pages with info on both sides of those pages. Perforations are intact with the exception of the cover page. There are 2 pages filled with small ads (meant to be separated and used in newspaper ads?). Any information about it would be greatly appreciated. I have considered framing each page individually.
