Although the bulk of the collection consists of postcards that document Colton's extensive travels, there is considerable information on her activities as a woman suffragist. Colton was a founder of Toledo's League of Women Voters in 1921, a member of the National Woman's Party in the 1930s, and served as a delegate to Carrie Chapman Catt's Woman's Centennial Congress in 1940. Materials in the collection include pamphlets, correspondence (1909 -1961), clippings, and autographs.
