This is a panel from an American League ball that was very likely used during the 1910 season. Can anyone recall ever seeing another OAL ball with this BB Johnson/1910 stamping? There are a few TJ Lynch/1910 National League balls out there, but I've never seen another example of an American League ball with a 1910 stamp.
This particular ball also has the much rarer April 6-09 patent date.
