Insects and butterflies became a serious subject for printed illustration long before they appeared in commercial design, driven by the 18th and 19th century appetite for natural history documentation. Engravers and lithographers produced detailed plates for scientific journals and collectors, where accuracy was the point and the results happened to be beautiful. That tradition carried into 20th century commercial work, where the forms showed up in travel, botanical, and decorative contexts. The pieces shown here are period originals from across that span.
