Ingersoll's liquid rubber paint.
A paint manufacturer's colour card issued by O.W. Ingersoll in 1910, offering liquid rubber paint to builders and property owners in the United States. The picture shows a sample sheet of numbered colour swatches with names such as Kansas Stone, Pearl Gray, Olive Green and Light Lead, priced per gallon. A designer could take from it a set of muted, earthy paint tones arranged as a clean grid of labelled chips.
