Scientific American, Vol. 87, No. 8 (August 1902)
An August 1902 issue of Scientific American, the weekly New York technology magazine read by engineers, inventors and mechanically minded general readers. The plates are dense wood-engraved and halftone cuts of stationary gas engines, flywheels, pumps and locomotives, many lifted from advertising pages with display type crowding the image, offering heavy-black machine silhouettes and hatched ground shadows for collage.
