ive figured out all the names on the ball, except 1 or 2 i cant read due to fading... oh well...

Wally Moses
Tommy McBride
Don Gutteridge
Rip Russell
Bob Doerr
Ted Williams
Bob Klinger
Earl Johnson
Rudy York
Dom DiMaggio
Bill Butland
Joe Dobson
Sam Mele
Tex Hughson
Micky Harris
Mel Parnell
Harry Dorish
Roy Partee
Hal Wagner
Eddie Pellagrini
Bill Zuber
Johnny Murphy

that puts the ball at 1947 because York played for both the Red Sox and White Sox in 1947, and retired with the A's in 1948... 1947 was also the last year Bill Butland played in the majors... 47 was Sam Mele's rookie year, Bill Zuber was only there in 1947 as well...

it was also the year that "The Kid", Williams won the triple crown... and the year he almost won MVP as well (he won 2 other times), but lost to Joe Dimaggio with 201 votes to Joes 202...
