I am typically quite good at spotting signatures however this one has me stumped. I have figured out every signature on this ball but the bottom one shown below. The list of other players is (in case it helps) :
Zachary Wheat
Ed Roush
Stanley Coveleski
Casey Stengel
Luke Appling
Sam Rice
Chas Gehringer
Roy Campanella
Joe Medwick
Dizzy Dean
Pie Traynor
Ted Lyons
Thanks guys!
