Keystona flat finish: "nature's harmony."
A 1913 trade catalogue issued by the Keystone Varnish Co. to promote its Keystona flat finish for interior walls, with each plate pairing a photograph of a finished room with colour swatches. It was aimed at architects, decorators and builders choosing paint for churches, homes, hospitals and public buildings. The photographs show painted interiors of pews, columns, parlours and a Senate chamber, offering designers examples of muted wall tones, woodwork and period detailing in real settings.
