[Nature prints of leaves in Über die Nervation der Pflanzenblätter]

Pokorny, Alois, 1826-1886. Uber die Nervation der Pflanzenblatter : mit besonderer Berucksichtigung der Osterreichischen Cupuliferen · 1858

"59 nature prints of leaves. The nature print is usually associated with the formed bas-relief print invented and produced by Alois Auer. This present form, also by Auer, is not mentioned in conjunction with this process but really is more important from a historical viewpoint because it is compatible with type. The detail is extremely fine and the prints look like photograms."--Hanson Collection catalog, p. 20
