Brand: L&C Hardtmuth
Quite a span of years shown here between the Austrian made Koh-I-Noor circa 1910 and the USA version at the bottom circa 1970's.
L&C Hardtmuth was formed in 1790 by Josef Hardtmuth in Vienna, Austria. In 1802 he patented the first pencil lead made from a combination of clay and graphite, and in 1848 the company was moved to the city of Budweis in what is today the Czech Republic. In 1888 they introduced the KOH-I-NOOR pencil, named after the largest known diamond in the world at that time. Today the company operates under the name KOH-I-NOOR HARDTMUTH.
