Based on the type style used for the Superior Sign and Chart Printer No. 929, this simple and clean sans serif font was perfectly suited for use by teachers in the classroom and for businesses and organizations that needed to make signs, price cards, charts and notices. Digitally redrawn as Schoolroom JNL, it is available in both regular and oblique versions. The Superior Marking Equipment Company [formerly of Chicago] was not only a major supplier of materials for the rubber stamp industry, but for most of its existence manufactured date and numbering stamps, sign and chart printers (such as the one used for this font), and a line of children’s printing toys (amongst other items).
