Harold L. Doolittle's collection of etchings, engravings, and lithographs mostly comes from the first 50 years of the 20th century and represents a large number of artists, some more famous than others. Doolittle himself contributed more than 30 of his own etchings, all of which are landscapes. There are sketches of Yosemite, California hills, mountains and more. Other art in the collection, especially from the Chicago Society of Etchers and the Society of American Etchers, takes a similar approach. The oldest print dates to 1799 with Francisco Goya's “Ya es Hora," one of several 18th and 19th century works. Goya is joined by other well known artists including Gustaf Dalstrom, George Elbert Burr, Maxime Lalanne, Richard E. Bishop and Charles A. Platt.
