I have found that there are 4 variations to this card. 2 front variations with normal backs and 2 back variations with normal fronts.
Front #1: The Yellow blob in the Yankees "Y" letter and on his face has a normal (no slash in record line) on back.
Front #2: The blue line above the "EE" in Yankees has a normal (no slash in record line) on back.
Both of the back variations have the normal front:
Back #1: The slash in the record line is broken into two parts and is thin. It also misses the "G" in Batting.
Back #2: The slash in the record line is a single slash and is wider than the broken, thin slash. And it touches the "G" in Batting.
That is all I have found so far.
Both backs variations are shown below Al's cards:
