    Abstract: A multi-layered and quick change signage system is provided. A frame carries a transparent cover sheet and behind the transparent cover sheet the frame carries a plurality of opaque sheets, each of which contains a different graphic image. The transparent cover sheet also carries alphanumeric information such as a person's name and title. The user of the sign may quickly change the material displayed on the sign by simply changing the opaque sheet which is mounted immediately behind the transparent cover sheet. A non-glare plastic lens is carried on top of the transparent cover sheet. The signage system is particularly useful in conjunction with office cubicles.
