A.J. Schumann, a Chicago photographer issued a eight real photo postcard set of Chicago baseball stadiums in 1908. This shot shows the ornate main entrance in 1908, the first year the Cubs were formally known as the “Cubs”. Note the cub figures holding up the oriole window on the ticket booth. Also note the statues on top of the ticket booth.
