Brand: Eagle Pencil Co.
Made in: USA
Rare Eagle Pencil Co. These pencils can be found in the different sets once produced by Eagle. I can confirm these ones are coming out of a large boxed set but I cannot confirm if that's the only place they were sold.
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 is today a division of Newell Brands).
