Original 1943 electrical trade vintage ad for LAPP INSULATOR COMPANY.  Main office and plant was located in Le Roy, NY.

Manufacturers of Porcelain Insulators.

Proving Ground For Insulators.

The temperament of the Lapp organization is that d dissatisfaction with existing methods, existing designs. It is the spirit which produced the Line Post and which made necessary the Lapp laboratory, a corner of which is photographed. No sanctum sanctorum, this laboratory is truly an engineer's workshop, in continuous day-to-day use, testing, discarding, proving new designs.

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.
