Ambler asbestos building lumber.
This is a 1917 trade catalogue issued by the Keasbey & Mattison Company of Ambler, Pennsylvania, promoting its asbestos-cement building lumber for builders and architects. The photographs show interiors partitioned with panelled walls, a stair and corridor, and a long factory-style building with a glazed facade, documenting the material in use. A designer could take from them the grid of panel seams, the wainscot-and-glazing rhythm, and the plain industrial character of early twentieth-century walls.
