Abstract: A business form uses a dual label construction to advantage, particularly in association with express delivery forms. A first sheet of paper has a first face with indicia and a second face with a first pressure sensitive adhesive system. A second sheet, substantially the same size and shape as the first sheet, has a first face, and a second face with a second pressure sensitive adhesive systems. The adhesive systems preferably are alternating strips of pressure sensitive adhesive release material, with small gaps between them, so that when the second faces are placed in face-to-face engagement with each other they will separate, providing adhesive on each of the second faces. The second sheet may be a substantially transparent plastic such as polyester, which may be placed over the first sheet, to protect it, after the first sheet has been adhered to a surface (e.g., a package for express delivery).
