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 three women, styled as witches, stirring a bubbling cauldron while a harried-looking man works in the background. 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.”
