Original 1943 electrical trade vintage ad for AMERICAN LAVA CORPORATION.  Main office and plant was located in Chattanooga, TN.

Manufacturers of Ceramic Insulators. Where the going is Toughest, you'll find AlSiMag.

Tank radios must be compact. Above all else, they must be dependable - able to withstand terrific vibration, jolts, and jars. They must operate under extremes of heat and cold. They must not fail. That is why you find more and more tank radios of Allied Nations equipped with AlSiMag steatite ceramic insulators - compact, tough and dependable.

Unbound from a 1943 electrical industry magazine, this unique old one-page advertisement would display beautifully matted and framed. Nice graphics. World War 2 propaganda. A fabulous addition to your retro electrical library.
