Glass, paints, varnishes and brushes

"Originally this book was planned to be merely a catalogue, though a highly comprehensive and serviceable one, of the manifold products of the Pittsburgh Plate Glass Company. Since the objective of this Company during the forty years of its existence has been on Service, and Service is watchword, this catalogue likewise was designed to serve the dealer, and through him the ultimate consumer, with sincerity and helpfulness far beyond the ordinary. The work has grown on our hands; the book has become a volume; in smaller compass it was impossible to carry out our ideal."--Introductory note.
