Here is a vintage cover of a booklet that was published for the Russell Grader Mfg. Co. of Minneapolis, Minn., circa 1916. This booklet contains a wide variety of interesting material and information, including: graph paper pages, maps, one-page calendars for 1916 and 1917, as well as random data that ranges from: time required for digesting food, antidotes for poisons, a six percent interest table, to: brief business laws and points of Constitutional Law. The booklet also includes images and information about equipment sold by the Russell Grader company, some of which I will include in a separate blog post.
