"KODAK" Is our Registered and common law Trade-Mark and cannot be rightfully applied except to goods of our manufacture. If a dealer tries to sell you, under the Kodak name, a camera or films, or other goods not of our manufacture, you can be sure that he has an inferior article that he is trying to market on the Kodak reputation. If it isn't an Eastman, it isn't a Kodak. EASTMAN KODAK COMPANY, ROCHESTER, N. Y., The Kodak City. "Mention the Geographic--It identifies you."
