  • Patent number: 4777747
    Abstract: An inexpensive, quick change pricing display on a sign board employs one or more basic numerical arabic figure eight digits of a segmented construction. Each basic numerical eight is made up of designator segments that may have contrasting color with respect to a viewing background of the display or sign. Numerical digits of zero through nine are selectively formed on each basic eight by applying or removing covering strip segments or elements which may be of the same or a different color as the viewing background to selective designator segments of each basic eight in such a manner as to leave exposed or to present color segments that represent the desired numerical digit.
