Magnet pictures the cover of a 1905 amateur baseball yearbook for Minneapolis - St. Paul in Minnesota, published by the A. G. Spalding Company.
Company co-founder Albert Goodwill Spalding (1850-1915) was a professional baseball player with the Boston Red Stockings and the Chicago White Stockings (forerunner to today's Chicago Cubs). According to one source Spalding's .796 career win percentage is the highest ever for a pitcher.
When this yearbook was published there were 14 retail Spalding stores and the company also manufactured equipment.
Baseball was thriving in Minneapolis - St. Paul in 1905 with 2 teams as charter members of the new American Association minor league. Found this fun website filled with info about St. Paul's 1902 baseball players.
