Here is a biography that I found on line, from SABR, of Charlie Ferguson. Ferguson was one of the stars of the Natinal League when he fell victim to typhoid fever and died just prior to the 1888 season. To honor him, Goodwin & Co continued to issue his Old Judge cards through 1889. The picture in the article is not Ferguson, but is Jim Tyng.
