My father worked for Moore Business Forms his entire career which ended up being nearly 45 years at his retirement. He used these rulers exclusively to draw forms both at the office and many a night at our family kitchen table. It was always fascinating to watch him create so many forms for so many great companys. I have one of the rulers to this day as he gave to me when he retired. Never knew I would have piece of American History in my desk drawer.
