Handbuch der Erdkunde
Gustav Adolph von Klöden's Handbuch der Erdkunde, a German geography handbook of 1859 written for secondary-school teachers and students. The wood-engraved figures are small captioned diagrams of physical geography \u2014 volcanic cones, folded and tilted rock strata, river deltas, valley profiles \u2014 drawn in fine parallel hatching that reads as both texture and terrain, useful as line-art fills, cutaway schematics, or ground patterns.
