A paper composite for use on billboards, including at least one water-resistant paper outer layer impregnated with a polymeric resin, and having one or more pigmented or clear coatings suitable for high quality printing on the surface of the paper, the composite optionally also including a reinforcing lightweight polymeric fabric. A method of applying a visible textual or pictorial image to a billboard includes attaching a composite of this invention, with an image on it, to the billboard. A method of forming a composite of this invention includes adhering together a polymeric fabric and a paper sheet and, either before or after the adhering step, impregnating the paper sheet with a first synthetic polymeric resin in an amount sufficient to render the sheet water-resistant and thereafter applying a coating layer on the paper sheet.
