Thin filmed thermoplastic material wall coverings having a preprinted image thereon and provided with a static electrical charge for securing the coverings to a surface. The wall covering may comprise posters, maps, and the like, and the image is printed on the film by means such as silk-screening. The static electrical charge is sufficient to removably secure the film to a wall surface, a window, or the like, and allows for relocation of the covering without damage to the surface upon which it is secured. The coverings may be packaged individually, or be dispensed from a continuous roll. Preprinted maps adherable to a window surface such as a windshield of an automobile are provided.
