Portrait of Curt Flood and Bob Gibson, Inscribed to Flood by Gibson, 1967-1968

St. Louis Cardinal outfielder Curt Flood and pitcher Bob Gibson had been close friends since their days in the minor leagues. In the 1960s, the two along other African-American ballplayers within the organization became increasingly outspoken about the segregationist aspects of the Cardinal operation. Their leadership brought about change. Bob Gibson signed this photo, "To my Roomie with much respect."
