Grover Cleveland Alexander is without a doubt one of the best pitchers of all time and he gets absolutely no love from anyone. The man won 3 pitching triple crowns in 6 years from 1915-1920. Oh don't forget he also had the lowest ERA in 1917 and 1919. Had he pitched more than 3 games in 1918 I'm sure he would have had the lowest ERA then too. He was an absolute machine. This happens to be an extremely nice autographed with his full name, he signed GC Alexander for the most part, government postcard. His autographs are scarce and very sought after especially in this condition.
