Overview
This is a specialized brass printer's and typographer's layout ruler, designed to measure character counts and point sizes for hot-metal typesetting. It features dedicated scales for 12-point and 10-point typewriter spacing, alongside a detailed character count reference chart at the base. It is a highly functional tool from the golden age of American print advertising and newspaper publishing.
Story
Before digital screens, Chicago's Ludlow Typograph Company revolutionized print. This brass ruler was the secret weapon of layout artists, translating typewriter text into perfectly spaced hot-metal headlines.
Maker / Origin
The Ludlow Typograph Company, founded in Chicago in 1906, was a titan of the printing industry, famous for its hot-metal typesetting machines used for headlines and display advertising. While Linotype dominated body text, Ludlow was the king of large, bold display type. Their specialized brass tools were prized by compositors for their precision and durability in busy, ink-stained print shops.
Condition & Value
The ruler shows honest wear consistent with use in a print shop, including minor surface oxidation, light scratches, and some rubbing to the black enamel finish. The brass has developed a pleasing, authentic patina.
