Bay State waterproofings.
A 1925 trade catalogue issued by Wadsworth, Howland & Co. of Boston and aimed at builders and architects, promoting paints, stains and waterproofing for concrete and masonry. The photographs show finished houses in stucco and concrete, each treated with the company's coatings, and a designer could take from them the look of smooth, lightly tinted exterior walls set against palms and clipped lawns in the 1920s Spanish and Mediterranean revival manner.
