This is a 1964 ad for a Los Alamos Scientific Laboratory! The size of the ad is approximately 5x11inches. The caption for this ad is 'By taming the awesome energy of the hydrogen bomb in a reactor operating at stellar heat, man may produce from sea water enough power to light the world' The ad is in good overall condition, with a piece of the corner missing from the upper right. This vintage ad would look great framed and displayed! Add it to your collection today!
