Original 1943 electrical trade vintage ad for BELL TELEPHONE SYSTEM. 

Reason for Confidence.

More than ninety per cent of American scientists are engaged in beating the Germans and Japanese. More than ninety per cent of American scientific laboratory facilities are devoted to the same task. American scientists are working at this job six or seven days a week, long hours, with few interruptions. Pictured is a new building of the Bell Telephone Laboratories.

Unbound from a 1943 electrical engineering 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.
