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 using a complicated make-shift apparatus 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.”
