Buffalo Bisons MiLB Dad Ballcap

History: The Bisons joined the International League in 1879 as one of the league's founding members. The league still exists today, making up half of the Triple-A minor league system. The 1959 ballcap celebrates the Bisons' pennant-winning season, where they ran away with the league led by the hitting of Cuban-born Panch Herrera, who also was the International League's MVP that year.
