(Band 1): Fünfzig Illustrationstafeln mit beschreibendem Text
Kunstformen der Natur, a German plate book of fifty chromolithographed illustrations edited by Ernst Haeckel and issued in 1899 for a scientific and general readership, held by Heidelberg University Library. The pictures are numbered plates of marine organisms drawn in precise, symmetrical detail, showing radial and geometric forms that a designer could use for ornament, pattern, or botanical-style layout.
