"Mention the Geographic-It It Makes No Noise! Why submit to the mental discomfort caused by the sound of flushing the ordinary noisy closet? The Trenton Potteries Company SIWELCLO Silent Closet operates so quietly, when properly installed, that it can't be heard outside its environment. It was designed to be silent, yet no sanitary detail has been neglected. Even if its highly glazed surface should be accidentally chipped off, it would still be white, and impervious to grease and acids. Architects and plumbers recommend the Si-wel-clo and all our other sanitary products. Booklet R-27 "Bathrooms of Character" shows plans and designs. May we send it to you? THE TRENTON POTTERIES COMPANY Trenton, N. J., U. S. A. The Largest Makers of Sanitary Pottery inU.S.A. identifies you."
