Speaking of early 20th-century semiprofessional baseball in Chicago, Scott Simkus has posted photos of Gunthers Park, ca. 1904, and the Pyotts club in the early 1920s, courtesy of Tom Niesen.  Tom is the great-great-grandson of William C. Niesen, who owned both clubs.  These clubs were sometime members of the famous Chicago City League and frequent opponents of the Leland Giants and their successors the Chicago American Giants, as well as other African American clubs (not to mention the Cuban Stars).
