Brand: Eagle Pencil Co.
Made in: Germany
This Eagle comes packaged in a wrapper marked Berolzheimer, Ilfelder & Co. patented April 3rd, 1860; Prize Medal London 1862. My guess is mid 1860's. Appears to be the collaboration of Berolzheimer and Illfelder prior to actually starting the Eagle Pencil Company here in the USA.
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).
