Official printed scorecard for "Class Day" in 1882, for a game pitting Harvard's 1877 and 1882 teams against one another.  Though the game itself is unsecured, the 1877 team does include Jim Tyng, the first catcher to wear a catcher's mask.  Some areas of discoloration are evident, likely caused by being stored adjacent to acidic paper over the years.  Regardless, an interesting document of early collegiate baseball including a pioneer in Jim Tyng.
