Official American League (Barnard) ball signed by Hall of Fame shortstop Joe Cronin across the sweet spot. Cronin's signature has been scripted in black fountain pen and grades 4/10 (a few portions of the signature are obscured by abrasions). There is a second black-ink signature on a side panel, but it is no longer legible. This ball dates to the 1928-31 manufacturing period so there is the possibility it was signed by Cronin during his 1930 MVP season. The ball displays numerous heavy abrasions throughout and a few areas of staining. Fair to Good condition. Full LOA from PSA.
