The California Historical Society strives to preserve the history of California. Discover printing and lithography in the West, as well as antique posters and maps. Exhibits offer fascinating insight into the daily life in California, including a horseless carriage (or so reads the license plate). You'll also find extensive collections of fine art, photographs and manuscripts, including Gold Rush era diaries and letters. The museum has a bookstore with titles on almost anything you would like to know about California from its earliest days to the present.
