Marvelous baseball signed in blue ballpoint on the sweet spot and side panels by ten, including six Hall of Famers: Rogers Hornsby, Jimmie Foxx, Lefty Grove, Bill McKechnie, Bill Terry, and George Sisler. Other signers are Charlie Keller, Eddie Rommel, Mrs. John McGraw, and one other. In very good to fine condition, with light overall soiling. Accompanied by full letters of authenticity from PSA/DNA and Beckett. Notably, Hornsby, Terry, and Sisler combined for six seasons with .400+ batting averages, with Hornsby accomplishing the feat three times. An uncommon and very desirable combination of baseball's great early stars.
