Just picked this up, the backstory is the ball was acquired during a Washington St Louis game in the early to mid30's standing along the railing/fence as players were coming by. While most names are legible - there are a couple that I can't make out.
Names I recognize or was able to figue out: Rogers Hornsby, Joe Judge, Buck Newsom (?) on sweet spot, Buddy Myer, Charles O'Leary, Buddy Lewis, Red Kress, Bucky Harris, Grover Hartley, Jake Powell
But I can't make out the two signatures above Jake Powell. I was targeting 1934 -- but figured someone on here might now.
