Players were recruited from hotel employees - Waiters, busboys, and porters. The Royal Giants traveled all over the state competing in an informal “hotel league” and became one of the top clubs of the independent era that existed before 1920.\n\n","images":["https://cdn.shopify.com/s/files/1/1487/1618/files/21770833_02.jpg?v=1706719542","https://cdn.shopify.com/s/files/1/1487/1618/files/21770833_03.jpg?v=1706719543","https://cdn.shopify.com/s/files/1/1487/1618/files/21770840_03.jpg?v=1706719545","https://cdn.shopify.com/s/files/1/1487/1618/files/21770833_04.jpg?v=1706719545"],"price":28,"currency":"USD","in_stock":true,"inventory_qty":39996,"dynamic_pricing":false,"listed_at":"2026-06-18T20:30:38.043Z"},"share_url":"https://firestarter.network/l/lst_Eq0Ufscg","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
