Abstract (en)
Display card for numerical information with at least a base surface of background colour and at the front thereof, in mirror image, one or more numerical markings consisting of seven segments of another colour, which markings each essentially have the form of an eight. A layer of clear transparent material, which can be written on, extends at the front on top of the numerical markings and the base surface so that any desired number can be displayed by covering particular segments of the numerical markings by means of ink of the background colour. The ink is of a composition which is removable so that any numerical display can be altered. Alongside the base surface with numerical markings, other surfaces with text and/or symbols may be vided between the back surface and the layer which can be written on.
