ABSTRACT:
Existing illuminated signs required skilled workers to replace or change the sign face. The present sign system allows the illuminated faces to be rapidly and easily changed by non-skilled workers. Transparent or translucent plastic envelopes are used to support color transparencies which form the sign faces. The envelopes are easily slipped into and out of the display position. The sign system is particularly suited for use as point-of-purchase advertising in grocery store aisle markers.
