Discloses a method of making scanning hooks with a release agent on the label attachment tab. Stock is formed by laminating a plastic sheet which will provide the main carrier body of the overlay and a thin film which has a release agent strongly bonded to its outer surface. The film is bonded to the main plastic layer, such as by an adhesive. Overlay blanks are cut from the resulting laminate stock as by die cutting. The overlay blanks then are bent and mounted on scanning hooks, with the tab portion extending essentially vertically and presenting an outwardly exposed release surface which provides ready appliability, removability and replaceability of merchandising labels which bear information related to the products supported on the hanger.
