One-page handwritten letter, dated April 21, 1908, signed by heavyweight boxing champion John L. Sullivan, who was known as the “The Boston Strong Boy.” In his letter, written on “Hotel St. George” (New York) letterhead to Arthur T. Lumley, Sullivan apologizes for not seeing him when Lumley tried to visit the day before. In part: "Friend Arthur - You must not censure me it not seeing you when you called the other day. It is unfortunate for good people to be turned down. . . . I myself have always had a great deal of admiration for you personally and still hold you in high esteem. . . ." The letter is signed “John L. Sullivan.” Both the text and signature are scripted in black fountain pen and grade 7/10 overall.

A. T. Lumley was a former editor of the “Police Gazette,” which had a major influence on pugilism at that time. Lumley was also a close friend of Sullivan and served as Sullivan’s fight manager during certain portions of his career. Sullivan, considered a legendary pugilist in both the bareknuckle and gloved style of fighting, is credited with helping popularize the latter. He participated in the last world heavyweight title fight with bare knuckles, beating Jake Kilrain in a grueling battle of 75 rounds, and the first gloved bout for the world heavyweight championship, losing to James J Corbett in the 21st round. He is truly an icon and innovator and is often regarded as America's first sporting celebrity and superstar. Indeed, it can be said that his popularity was responsible for assisting the advancement of American sporting journalism and coverage. He is an original member of the International Boxing Hall of Fame in the first induction class of 1990.

The letter (5.5x8.5") displays two horizontal folds and is slightly toned. In Very Good to Excellent condition overall. Accompanied by the original mailing envelope, which is postmarked "Brooklyn N.Y. April 21 1908" (6x3.5"; VG). Full LOA from PSA.
