Scientific American, Vol. 60, No. 12 (March 1889)
An issue of the weekly American technology magazine Scientific American, published by Munn & Co. in New York in March 1889 for inventors, engineers and general readers. Illustrations are wood-engraved machine studies — furnace sections with hatched flames, locomotives in profile, bench tools and a typewriter — with clean outlines and crosshatched shading that cut well to silhouette or line art.
