Scientific American, Vol. 19, No. 2 (1868)
Scientific American volume 19, number 2 from 1868, a weekly American periodical of mechanical and technical news, written for inventors, engineers and general readers. Its pages mix patent-machine engravings with captioned line drawings of devices such as a forming machine, a blind opener and a corn planter, plus a scene of hands on a planchette-style board. A designer might take crisp black-and-white hatched linework, tidy captioned labels and compact diagram layouts.
