Original electrical trade vintage catalog for WESTERN LITHOGRAPH COMPANY, was located at 600 East Second Street, Los Angeles, CA. Manufacturers of E-Z Code Labels, for every electrical installation, quickly coded for immediate identification. E-Z-Code labels represent a fast, simple and economical method of coding wire, conduits and cables for assemblies, maintenance and repairs. Disbound from a large 1944 electrical construction materials book, this unique old one page technical brochure would display wonderfully matted and framed. A marvelous addition to your retro electric equipment library.
