ABSTRACT:
Sign having self-storing characters which are quickly changeable. The face of the sign has a patterned array of openings juxtaposed against a contrasting background. The background may be supplied by color contrast and/or by illumination. Shutters are mounted for sliding or pivotal movement for selectively closing the openings so that the remaining exposed background areas define visual information such as symbols or characters. Alternatively, the shutters may be rotatably mounted in the openings and have opposite sides which, respectively, contrast with and match the sign face color.
