Original vintage architectural trade magazine ad for THE TRENTON POTTERIES COMPANY of Trenton, NJ. Dental Lavatory for Bathrooms. Every architect must appreciate the need of such a fixture for homes of refinement, in homes of people who can and will pay for this sanitary convenience. For it isn't clean to wash the teeth in the same basin you wash your face. The Sanitary Dental Lavatory of Vitreous China obviates all this. Very effective in Dentists and Doctors Offices, Steamships, and Cars. Old 1912 construction industry advertisement.
