A graphic novel biography of Puerto Rico's greatest baseball star. 21 is an all-ages graphic biography of baseball star Roberto Clemente: No other baseball player dominated the 1960s like him and no other Latin American player achieved his numbers. 21 chronicles his early days growing up in rural Puerto Rico, the highlights of his career (including the 1960s World Series), the prejudice he faced, his private life and his humanitarian mission. Santiago captures the grit of Clemente's rise from his impoverished childhood, to the majesty of his performance on the field, to his fundamental decency as a human being, in a drawing style that combines realistic attention to detail and expressive cartooning.
