NVF Company was a manufacturer of laminated plastic plates and sheets composed of only cellulose; the material is called vulcanized fibre. Initially named the National Vulcanized Fibre Company, it was formed in 1922 by Israel Way Marshall (1850-1911) and Thomas Elwood Marshall (1855-1929) in Yorklyn, Delaware. NVF Company was one of the three largest fibre companies in the country and eventually dissolved in the early twenty-first century. The NVF Company collection consists of records beginning in the 1870s, before the official creation of the company, and continues until the dissolution of the company. These materials include the history of the Marshall family, the formation of the National Vulcanized Fibre Company, administrative and presidential papers, publications and reports, marketing and publicity materials, subject files, labor contracts, employee grievances, and arbitration cases.

The collection primarily consists of images featuring the Marshall family and their relatives and friends, both in formal group portraits and more casual poses.
