Key to Ray's New Arithmetics (Primary, Intellectual, and Practical)

Got this copy of Key to Ray's New Arithmetics published by Mott Media. It covers the primary, intellectual, and practical sections. The cover has some cool ornate detailing and it's in decent shape for its age. Good for anyone into old school textbooks or homeschooling with the classic Ray's series. Just a solid vintage math resource to have on the shelf.
