Original old trade magazine ad for GENERAL ELECTRIC COMPANY, 1 Plastics Avenue, Pittsfield, MA. Plastics Vocal Cords for Our Fleet. When her big guns spoke, a warship's loud speaker system didn't. Gun blast was too much for the loud speaker diaphragms. They failed when needed most for battle commands. This naval problem was solved by GE's complete plastics service They developed a special phenolic-treated cloth that can be molded as thin as .003 in and drawn to domed contours of acoustical precision. This 1947 magazine advertisement would display beautifully matted and framed.
