Abstract: An advertising placard (20) having a substrate (30) and coloration material (34) is utilized to provide an unobtrusive and nondistracting advertisement on internal viewing surfaces (22) in commercial aircraft passenger cabins (24). The substrate (30) is preferably thin and transparent, and the coloration material (34) preferably has substantially the same color hue as the viewing surface (22) to which it is applied. Further, the coloration material (34) preferably has a color lightness within approximately &Dgr;7 of the color lightness of the viewing surface (22).
