Microtonic “Van Dyke” Eberhard Faber
I found this box of pencils among a couple other items in my father’s old drawing and drafting supplies. He is not alive for me to ask but these items could have also been his grandfathers.
Eberhard Faber emigrated from Germany to America in the 19th century, founding his own pencil company. Today his company is apart of Faber Castell.
