Brand: Berol Pencil Co.
Made in: USA
Very rare Ben Franklin 501. This pencil appears to be made with the EPCON process as pioneered by Empire.
The company was originally founded in New York City by the Berolzheimer family, and in 1969 became part of Berol Corporation. Berol was purchased by Empire in 1986, which was purchased by Sanford in 1995 (which has been a division of Newell Rubbermaid since 1992).
