The Giants' accomplishments took place against an historical backdrop of a change in the African-American experience. The original players from Jacksonville, Florida, joined the northward black migration during World War I. The team was named after Harry Bacharach - an Atlantic City politician running for mayor - as a way to keep his name before the city's black community. The Giants were immediately successful, and soon played the best semi-professional teams in their region, as well as the top black teams from the East and Midwest. They entered the first Negro league on the East Coast in 1923, and won the league championship twice before the decade ended. This book chronicles the Giants' pivotal role in the development of black baseball in Prohibition-era Atlantic City, and the careers of the men who made it possible.

Cumberland Posey began his career in 1911 playing outfield for the Homestead Grays, a local black team in his Pennsylvania hometown. He soon became the squad's driving force as they dominated semi-pro ball in the Pittsburgh area. By the late 1930s the Grays were at the top of the Negro Leagues with nine straight pennant wins. Posey was also a League officer; he served 13 years as the first black member of the Homestead school board; and he wrote an outspoken sports column for the African American weekly, the Pittsburgh Courier. He was regarded as one of the best black basketball players in the East; he was the organizer of a team that held the consensus national black championship five years running. Ten years after his induction into the National Baseball Hall of Fame, he became a member of the Naismith Memorial Basketball Hall of Fame-one of only two athletes to be honored by two pro sports halls.
