Scientific American, Vol. 75, No. 21 (November 1896)
A weekly issue of Scientific American, published by Munn & Co. in New York in November 1896 for inventors, engineers and general readers following patents and new machinery. Wood-engraved and process cuts show typewriters, dynamos, cast-iron machine frames and shop interiors in dense black line, with hatched shadows and factory-window backgrounds useful for machine silhouettes and technical spot art.
