ABSTRACT:
An illuminated sign consisting of: a message carrying wall having a front display side and a rear side, with the message carrying wall having a portion that is opaque to block light transmission therethrough from a source on the rear side of the message carrying wall and a transparent and/or translucent portion that allows light transmission therethrough from a source at the rear side of the message carrying wall to produce an illuminated message that is visually detectable at the front side of the message carrying wall; and a lenticular structure at the front of the message carrying wall for intercepting light transmitted from a source on the rear side of the message carrying wall through the transparent and/or translucent portion of the message carrying wall to diffuse the light in such a way as to give the appearance of a light source being at the front of the message carrying wall.
