Series 10: Visual Material, 1844-2006

The visual material series consists of an assortment of photographic prints, negatives, glass plates, signage, logos, and copper printing plates. Photo subjects include group and individual portraits of field excursion participants and members, plants with and without disease, fungi, line drawings, insects, and subjects under a microscope. Some of the material is uncaptioned and undated. There is an original lockbox filled with copper printing plates etched with portraits that were printed in the club's publications.
