Barb, I'm nearly sure that no photographs of the Twain and Grant together were taken at the 1879 army reunion in Chicago. Twain's letters to Livy describe his doings there almost hour by hour, and certainly he mentions no photo session. Vol. II of Twain's Notebooks and Journals indicates many events and meetings involving the two of them in 1880 and later, but still before Twain's major involvement with Grant in the general's last year. One of your best bets might be Grant's visit to Connecticut when campaigning for Garfield in 1880. Twain introduced him. Later, the Notebooks and Journals suggest more than one get together in Grant's New York office. Have you tried this one?--Thomas M. Pitkin, The Captain Departs: Ulysses S. Grant's last campaign Carbondale, Southern Illinois University Press , 1973, There OUGHT to be such a photo! Yet I honestly can't recall ever seeing one. If someone knows of one, please answer on the Forum or send me a copy of your reply to Barb. Good luck. Mark Coburn
