The National Biscuit Company Salesman's Collection consists of materials for the use of National Biscuit Company salesman, including blank order forms, a student’s training guide, and a package catalog. Although none of the materials are dated, they may date from about the 1930s. possibly earlier. The order forms and student record book are empty, but a pasted in newspaper at the back of the packaging catalog suggests this may have been used by a salesman in Maine.

The catalog contains sample packaging for a range of products, as well as examples of different kinds of racks to present the products in store. The order forms are all unused, but have space for quantities, products, prices, and include a note on the use of display covers. The "student salesman's progress record" appears to have been a training tool. It walks through the company's training program, guided by the National Biscuit Company logo, and consists mainly of questions to be answered by trainees on the company, products, raw materials, processes, advertising, and even the use of forms.
