Original 1943 electrical trade vintage ad for INTERNATIONAL RESISTANCE COMPANY.  Main office and plant was located at 427 North Broad Street, Philadelphia, PA.

Manufacturers of Resistors.

"Knowledge, sir is of two kinds" -said Dr Johnson.

Wise old Samuel Johnson was not, we suspect, talking about the electronics industries, but his statement, like most basic truths, applies directly to the increasing search for knowledge among executives and engineers in this field. Here at IRC you will find a Service and Information Center staffed by electronic engineers of outstanding ability. Their work has two main purposes - to design, perfect and maintain the quality of IRC Resistors; to cooperate with you on Resistor applications of every nature.

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.
