Remarkable season pass good for admission to all Federal League parks for the 1913 season. While most collectors are likely aware the Federal League was considered a Major League by 1914-15, it is less well known that the league started the season prior as an independent minor league. Teams in the 1913 Federal League included the Indianapolis Hoosiers, Cleveland Green Sox, St. Louis Terriers, Chicago Keeley's, Covington Blue Sox (moved to Kansas City late in the season), and the Pittsburgh Filipinos. Graded VG 3 by PSA, the pass presents well with a hint of toning towards the bottom and right edges. Heavy staining does impact the reverse. An attractive memento from the highly collectable Federal League.
