This invention relates to retroreflective sheeting which has an image, such as an image. More specifically, the image has varying appearance at different angles of view. The retroreflective sheeting has a layer of transparent microsphere lenses, a transparent polymeric spacing layer underlying, contacting, and conforming to the bottom of the lenses, the spacing and conformation of which is critical to the optimal performance of the retroreflective article, a reflective layer having a top surface in contact with the back surface of the spacing layer and a topcoat and/or cover sheet overlying and conforming to the top surfaces of the lenses and having a flat top surface or face. In another embodiment, the retroreflective sheeting includes a pressure sensitive adhesive underlying and in contact with the reflective layer. The retroreflective sheeting has an image whose proportions are determined by a non-conformity of the reflective and spacing layer to the bottom of the lenses. The image of the present invention can range from conspicuous to inconspicuous and directional to non-directional.
