Heinz,” one page, 6.75 x 10, personal letterhead, October 16, 1907. Letter to Rev. Francis E. Clark of the United Society of Christian Endeavor. In full: “During my absence abroad this summer, an autograph copy of your book entitled—’A New Way Around an Old World’, was received at my home and just came to my attention yesterday. Be assured that I appreciate your kind courtesy and I have no doubt that I shall appreciate the story the book tells when I have the opportunity of reading it which I trust soon to have. With kind personal regards and a growing appreciation of what you are doing for the development of the work to which you have given your life, I remain, Yours sincerely, H. J. Heinz.” Affixed to a heavier 7.5 x 10.5 sheet with another letter to Clark affixed to the reverse. In very good condition, with intersecting folds, light scattered toning and soiling, and mirroring of ink from a different letter. Items signed by Heinz are very rarely offered for sale, and the clean signature at this letter’s conclusion makes it especially desirable. RRAuction COA.
