The Advertising and Promotional Collection contains materials for a wide variety of businesses and organizations in Lancaster County, including manufacturers, department and clothing stores, entertainment venues, grocery stores, restaurants, service providers, and social clubs. Of special interest is the use of both English and German in a brochure from the Great Atlantic and Pacific Tea Co., as well as in the soap-making directions from the Pennsylvania Salt Co. There are also a 1921 program from Lancaster's Colonial Theatre and boxing programs that list Lancaster native, Leo Houck.
