1941 Amateur World Series program. Cuban-printed event ephemera from one of the most important early international baseball tournaments, documenting the breakthrough moment of Venezuelan baseball on the world stage. The 1941 tournament was the fourth Amateur World Series, played in a round-robin format with nine national teams competing over several weeks. It became historically significant because Venezuela defeated the heavily favored Cuban team in a decisive playoff game to win its first international title, a moment that became known as the rise of the “Héroes del ‘41.”
