Scientific American, Vol. 91, No. 22 (November 1904)
An issue of Scientific American, the weekly New York technology magazine published by Munn & Co. in November 1904 for engineers, inventors, and manufacturers. Its pictures are coarse letterpress halftones and line engravings of machinery advertised and described in the trade: gasoline engines with heavy spoked flywheels, bench lathes, printing and duplicating machines, cement plant apparatus, all cropped tight against bold display type, useful as high-contrast industrial stock imagery.
