A thin polymeric strip material which is formed on one surface with a plurality of ridges and grooves defining a surface affording in the presence of light an optical image in space having an appearance other than that of a surface of said strip. The article may have a coating over the surfaces of the ridges affording a reflective surface and an optical image. Preferably an adhesive is applied on the strip material to bond the same to the surface of an article to afford ornamental and utilitarian properties to the same by providing a predetermined optical effect. |
