Abstract: Linear means, particularly for producing a mirror having a discrete transparent portion of a desired shape, configuration or ornamentation and having a backing which may have a discrete image of corresponding shape, configuration or ornamentation affixed in juxtaposition thereto, is set forth. The means of production of said mirror include providing, upon a glass surface, a layer of reflective substance, applying over said reflective substance, a layer of protective resist material which delineates, outlines and profiles said desired shape, configuration or ornamentation, then treating said coated glass surface to set said resist and washing the same to remove unprotected reflective portions delineated by said protective layer and exposed to said wash.
