October 12, 1961. From Warren C. Giles to Dr. Stewart D. Brown, Jr. One page typed on "National League of Professional Baseball Clubs / Carew Tower" letterhead. Near fine tri-folded letter with minor blue pen marking by previous owner. An attractive letter without any nicks or tears. Includes James Spence Authentication (JSA) certificate. In this letter, Warren Giles regrets to inform Stewart Brown, Jr. that he will not be able to attend an upcoming Capital City Club of Atlanta luncheon. Giles served as the president of the National League for eighteen transformative years. During his time as president, among other major changes, the Giants and Dodgers moved to California, and the Houston Astros, San Diego Padres, and Montreal Expos joined the NL. Notably, Carew Tower, which is stamped on this letter's letterhead, is where Giles maintained a professional office for his entire tenure as president. Today, the Warren C. Giles Trophy is awarded each year to the National League champion. Dr. Stewart D. Brown, Jr. was the son of an acclaimed surgeon who collaborated with Ty Cobb to erect a hospital and the Ty Cobb Museum in Cobb's hometown of Royston, Georgia. Stewart Brown, Jr. established the Ty Cobb Memorial Baseball shrine in honor of Cobb on Sept. 29, 1961, less than two weeks prior to the dating of this letter.
