This is a great mixed-medium set, as stars of American stage and screen have autographed the very symbol of America's pastime. These five celebrity baseballs are all autographed on either official National or American League baseballs, and signers include: Kirk Douglas, Bob Hope, Jimmy Stewart, George Burns, and Sammy Davis Jr "Peace." The signatures are in various condition, with Stewart's showing the most fading, and the average about 7/10.
