ABSTRACT:
Brass plaque indicia indicating products are provided according to the present invention which can be economically produced by stamping of brass plate. Prior to the present invention stamping of brass plate to define brass indicia was not economical relative to forging techniques due to the high amount of scrap brass plate which resulted by the stamping operation. The present invention recognizes that the scrap produced during this stamping of the indicia can provide a brass plaque having an interior which defines an outline of the indicia and if a background member is secured behind the brass plate this combination defines the desired indicia. Therefore by stamping of brass indicia and using the remaining scrap to define a further brass plaque which in combination with a background member defines the indicia, the stamping operation becomes very economical relative to a forging operation as two brass products for identifying indicia are produced by the one stamping operation. Furthermore, it has been found by providing a polished brass surface and a background member of contrasting color, the visibility of the indicium is greatly increased with decreasing lighting conditions relative to the recognition of the brass indicium itself. This increased visibility is due to the light reflective nature of the brass plaques and the contrasting color of the background member which advantageously diffuses light to further enhance the contrast.
