The two release sheets are separated by a score line. The first release sheet is of substantially identical dimension to the standard sized photograph to be mounted. The second release sheet is of substantially identical dimension to the mat to be mounted to the backboard. Removal of the center section release sheet allows for adhesive contact with and virtually automatic alignment with the standard sized photograph. Removal of the second release sheet framing the first release sheet provides an adhesive area to which the mat can be applied.

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.
