Imperial catalog

"Imperial Porcelain" has become a synonym for the highest grade product, at least where high-tension transmission insulators are concerned. The excellent record made by the imperial insulators in many of the largest long-distance transmission installations in the United States, especially on the Buffalo-Niagara Falls line, is in iteself a guarantee. The Imperial Porcelain Works, of Trenton, N. J., manufacturers of these insulators, will send interesting descriptive circulars on request.
