Proprietary (patent) medicine makers employed a wide array of advertising and marketing techniques to sell their products. The free sample, or trial size, was one of these. Dr. King's New Discovery, developed by Dr. Z. L. King of Elkhart, Indianna, was purchased by Herbert E. Bucklen around 1878. Bucklen spent lavishly on advertising which brought national recognition to his New Discovery and other medicines.
