TLS signed “T. Roosevelt,” one page, 6.75 x 7.5, Outlook letterhead, February 25, 1913. Letter to Richard Child regarding his future son-in-law. In full, “Dick Derby is all that you say he is. I did not realize that he was in your class. He is a very fine fellow. I will send you a copy of that address as soon as it comes out in the Historical Magazine.” Dr. Richard Derby would marry Ethel Roosevelt two months later. Mild spreading of ink in signature resulting in a somewhat fuzzy appearance, light mirroring of text from premature folding, and a touch of light soiling, otherwise fine condition. Auction LOA John Reznikoff/PSA/DNA and R&R COA.
