Original 1943 electrical trade vintage ad for STACKPOLE CARBON COMPANY.  Main office and plant was located in St. Marys, PA.

Manufacturers of Everything in Carbon but Diamonds.

Better Brushes for Today's Jobs.  Thanks to Stackpole's progressive engineering leadership.

Today, it is the rule rather than the exception when a set of brushes lasts the entire life of a fractional horsepower motor or generator. Even more important, is less spectacular, however, are the Stackpole engineered brush improvements for heavy-duty equipment.

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.
