Abstract: A sign structure having a copy board which is movable across the face of the structure and which releasably mounts display symbols such as numeric and alphabetic charactrers. The copy board comprises a frame which is mounted to the sign structure via rollers and may be positioned at will along the length of the sign structure adjacent to, overlapping, or removed from a vignette, etc., displayed on the sign face. Retainer bars extend between opposite sides of the copy board frame and are adapted for releasably mounting symbols by engaging slots formed in the symbols. Great flexibility is provided in positioning the symbols, for the copy board frame can be positioned at will along the sign, the retainer bars can be positioned substantially anywhere along the copy board frame in the direction perpendicular to their length, and the symbols can be positioned at will along the length of the retainer bars.

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.

Abstract: A support for a screen printed transparency or other photographic art work which may be raised on a track from a lowered ground level position to an upper position in a frame mounted on an elevated illuminated signboard. The support is fixed in the frame on the elevated signboard when raised.
