Printed TLS, signed in ballpoint, one page, 8.5 x 11, pictorial personal letterhead, no date [circa 1974]. An unsent form letter evidently intended for fans who had written to him. In part: “I was delighted to hear from you. You may not think so, but I really appreciate each and every letter that I receive. I feel good now. I’m in good shape and razor sharp. In case you were a little aprehensive [sic] regarding my upcoming fight, let me inform you that this is going to be the prettiest, most masterful upset that boxing has ever seen. I guarantee this, and I couldn’t be more serious….” The letter evidently dates to the months before the famous “Rumble in the Jungle” with George Foreman, during which Ali employed his famous “rope-a-dope” technique in scoring his historic victory. A touch of light handling wear and faint diagonal crease touching a few words of text, otherwise fine condition. Auction LOA Steve Grad/PSA/DNA and R&R COA.
