During the NSL’s 1932 season – the only year it was a major league – the Grey Sox played at the Cramton Bowl, which also hosted the Philadelphia Athletics for spring training. The park survives to this day and was renovated in 2011.","images":["https://cdn.shopify.com/s/files/1/1487/1618/files/21779362-1.jpg?v=1744400337","https://cdn.shopify.com/s/files/1/1487/1618/files/21779362-2.jpg?v=1744400337","https://cdn.shopify.com/s/files/1/1487/1618/files/21779362-3.jpg?v=1744400337","https://cdn.shopify.com/s/files/1/1487/1618/files/21779362-4.jpg?v=1744400337","https://cdn.shopify.com/s/files/1/1487/1618/files/21779362-detail1.jpg?v=1744400338","https://cdn.shopify.com/s/files/1/1487/1618/files/Brim-detail-updated_7823cbf6-9067-4245-b502-2f216002baba.jpg?v=1745347560"],"price":51,"currency":"USD","in_stock":true,"inventory_qty":49995,"dynamic_pricing":false,"listed_at":"2026-06-18T20:30:39.423Z"},"share_url":"https://firestarter.network/l/lst_HwhLs_jk","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
