The Giants had an integrated fan base, which was unusual for the time. Home games were played at Booker T. Washington Park in East Nashville. The team folded in the early 1920s when the Great Depression impacted all professional baseball, including the Negro Leagues.\n\n","images":["https://cdn.shopify.com/s/files/1/1487/1618/files/21770834_02.jpg?v=1706719574","https://cdn.shopify.com/s/files/1/1487/1618/files/21770834_03.jpg?v=1706719574","https://cdn.shopify.com/s/files/1/1487/1618/files/21770841_03.jpg?v=1706719578","https://cdn.shopify.com/s/files/1/1487/1618/files/21770834_04.jpg?v=1706719578"],"price":28,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-18T20:30:38.038Z"},"share_url":"https://firestarter.network/l/lst_kSAJ6FRZ","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
