The collection is comprised of documents and photographs from Lathen's labor and political activities in Vallejo. It ranges from a 1928 Plasterers' & Cement Finishers' Union Constitution to a 1995 holiday card from Bill and Hillary Clinton. Also included are brief letters to and from politicians Lathen supported, including Franklin & Eleanor Roosevelt, Henry Wallace, Estes Kefauver, Edmund "Pat" Brown, and Alan Cranston in the "Correspondence - Political" folder. "The Plasterer" folder preserves two issues of the Plasterers' Union publication that contain letters from Stanley Sapp. There are undated papers opposing the use of sheetrock in construction in the "Lathing and Plastering" folder.
