Series I. Personal Papers contains photographs of Clark, legal papers, and personal correspondence. The legal papers include an award against Clark, in favor of James Gordon Bennett, and Clark’s will along with two codicils. There are bills and receipts for artwork, and invitations and passes given to Clark over the years, including material related to the launching of the armored cruiser U.S.S. New York in 1891. Included in this series is a note about a portrait of Clark when he was on the Indiana; it appears that the note was written by former Peabody Museum Curator Lawrence W. Jenkins, but there is no information about why the note was written or when. Also included are materials related to a photography exhibit by Clark at the St. Botolph Club, a street directory, and Clark’s obituaries. There is also an auction catalog from Karl and Faber included in this series. It is dated 1931, nine years after Clark’s death, so it is unclear who added this to the collection or why, but it has been placed in this series because some of the auction items fall under Clark’s research interests.
