The photographs include one of the dog who inspired Jack London's novel The Call of the Wild; several of the Bond family's California home, on which London based the setting for the beginning of the novel; and forty-five commercially produced photos of the Klondike region and Dawson by E. A. Hegg and other photographers.The bulk of the collection is correspondence, which includes Bond's letters to his family from the Klondike, from Goldfield, Nevada in 1904, from Mexican villages under attack by Pancho Villa in 1918, and from hunting trips in Alaska in 1911 and Africa in 1927. It also includes his incoming and outgoing correspondence with business associates and friends, which documents mining ventures and other matters, including a plan to settle Boer refugees in Mexico. Bond's letters to Herbert H. White report intelligence about Germans in the American Southwest during World War I.The correspondence includes one letter from Jack London to Marshall Bond, in which London confirms that the character "Buck" was indeed based on the Bonds' dog, and Judge Miller's house in the novel on Judge Bond's house in Santa Clara.The collection also includes photographs taken in 1926 of surviving associates of Billy the Kid, a few World War I letters from the front, copies of newspaper articles by Bond, maps of the Yukon Territory, and a typescript of a book by Marshall Bond, Jr.
