St. Louis Cardinals Baseball Cap Worn by Curt Flood, 1965-1969

St. Louis Cardinal outfielder, Curt Flood, challenged the Major League Baseball's reserve clause in 1969. The reserve clause was used to restrict the movement of players and to control player salaries. Flood lost his court challenge, but opened the door for other players who would eventually become free agents. Flood used this baseball cap during his career in St. Louis.
