The bulk of the collection comprises wine labels and ephemera created by California winemakers and wine companies in the 1930s and 1940s. The core of the collection consists of wine labels printed by Lehmann Printing and Lithographing Co. in San Francisco in the 1930s and '40s. (Most undated labels fall into this group, although some may date from the nineteenth century). In addition to wine labels, the collection contains a small number of labels for beer and other liquor manufacturers in California, mostly dating from the 1930s and '40s.
