Abstract: A shipping and return mailing label includes three parts: (1) a shipping label, (2) a return label, and (3) an intermediate card connected to the two labels by lines of perforations, with the front face of all the parts of the label assembly being exposed as the label assembly is mounted on a backing sheet, so that, for example, bar codes may be directly printed on each of the three parts. The return label is coated with adhesive on its rear side, the card may be free of adhesive, and the shipping label may be of greater extent than the return label and the card, and may have stripes of adhesive located on its three free edges, so that the entire assembly, following printing, may be folded in a Z-shaped manner, and secured to a carton to be shipped.
