ALS signed “S. L. Clemens,” two pages, 4.5 x 7, black-bordered stationery, September 15, 1905. Clemens writes from his summer home in Dublin, New Hampshire to writer and editor [Norman] Hapgood (1868–1937). In full: “I am very glad McClure is to print it. I hope to remain undiscovered; in which case it will be pretty sure to do some good. I believe D— [Denil?] thinks you have injured his character. There is something impressively humorous about the idea of damaging the character of that abscess, that chancre. If you have to go to jail for lancing it, it’s an honor & I am ready to go shares; I’ll stand watch & watch with you.” Twain’s use of mourning stationery followed the death of his wife, Olivia, on June 5, 1904. The events to which Twain alludes are unclear, though it would seem that a pseudonymous letter or article by him was to be printed in McClure’s magazine. During the summer and fall of 1905 Twain spoke publicly on a number of issues, including corruption in politics and business, copyright law, imperialist atrocities committed by Belgium in the Congo, the “hopelessness” of Russia under czarist rule, and more. A subtle hint of faint scattered soiling, and heavy horizontal mailing fold, otherwise fine, bright condition. Auction LOA John Reznikoff/PSA/DNA and R&R COA.
