A built structure (10) having an upward facing surface; which supports a first image (11) is described. The upward facing surface is overlaid by the first image (11) in the form of first upwardly facing advertising indicia. The first image (11) is arranged for visibility from craft (13) passing over the built structure (10) and so as to be discernable by observers in the craft (13) when the craft (13) is within a predetermined legibility distance of the built structure (10). Revenue is derived from the upward facing surface. The first image (11) comprises an active image in communication with a local controller whereby the image (11) can be replaced by loading a fresh image from a local controller; and where the local controller is in communication with a remote computer adapted to communicate at least the first image to the local controller. |
