Based in New York City, with the earliest discovered online reference being for 1911 with offices at 86 Fulton Street, the Elbe File & Binder Co., made a wide variety of stationary supplies including this No. 91 series, (blind-stamped on folder verso) internal clasp-style folder believed to date from ca. 1920-40. In 1939, the concern moved their manufacturing facilities into 120,000 square feet of leased space within an old 19th century cotton and granite mill located in Fall River, MA at 649 Alden Street. By 1990, the company combined to become Elbe-Cesco, Inc., with a specialization in bookbinding. (the firm is still in business) In the present day, the former stone-clad mill building (as of early 2017) is being converted into market rate rental apartments.
