This reverse on glass sign has it's own folding cardboard light box assembly which provides the illumination on the piece. Very few of these are known to exist and this is a sound example. Only some moderate wear on the cardboard frame and some light surface rust on the original chrome frame around the piece. The mirror is sound, with no flaking and only some mild foxing and slight discoloration in the background of the mirror. Condition (Excellent). Size 13" x 9".
