Front and back of an illustrated color postcard advertising the products and services of the Eastman Organic Chemicals Department (Division of the Eastman Kodak Company). The postcard features a humorous depiction of a man rigging a complicated scientific apparatus around a building and through windows while attempting to brew his own chemicals. Postmarked from Rochester, New York, the postcard also includes a brief summary of Eastman’s available stock of chemical compounds as they pertain to the “chemical businessman.”
