Ink manufacturers took great pride in the quantity and consistency of their factory-made products. It was common to distribute brochures which were meant to educate customers about the production of ink and promote the company’s line. This example, from the Ruxton Ink Company, publicizes their major contract to produce ‘Uneeda Purple.’ The National Biscuit Company (now known as Nabisco) created one of the first mass market ad campaigns for pre-packaged food. It was wildly successful and Uneeda crackers became known by their purple box color and iconic raincoat-clad Uneeda Biscuit boy. The contract to produce Uneeda purple was the largest ink contract of the time.
