Abstract: This invention relates to a display layer adapted to be attached to a vehicle wherein the display layer is adapted to be secured to a support layer via at least one affixing means, and wherein the display layer is formed from at least one sheet of flexible material which in use is placed under tension in at least one direction. In preferred embodiments, in order to place the display layer under tension, the display layer is shaped with at least one side being inwardly contoured, and as such, the central portion of the display layer is placed under greater tension than the edges. Furthermore, the edges of at least the display layer may be configured to provide an anchor element that can be secured in an affixing means to provide the required tension.
