LOUIS CARDINALS\nHistory: Between 1953 and 1963, during what came to be known as the “Decade of Change” in baseball, six teams moved to new cities and four brand new ballclubs joined the majors.\nOne of the greatest hitters of all time, Stan Musial played his final season for the Cardinals in 1963. He finished his 22-year career with a .331 batting average and hit 475 home runs, and he set National League records with 3,630 career hits and 1,951 career RBIs. In his final game he went two for three and received a standing ovation from a sold out crowd in St. Louis.\nEbbets teamed up with Mitchell & Ness to create the Decade of Change Collection, honoring the era with period-accurate ballcaps like this one — handmade in the U.S.A. from genuine wool broadcloth and featuring an embroidery style typical of the time.","images":["https://cdn.shopify.com/s/files/1/1487/1618/files/20250903_EBBETSHATS3591.jpg?v=1757271541","https://cdn.shopify.com/s/files/1/1487/1618/files/20250903_EBBETS_HATS3592.jpg?v=1757703247","https://cdn.shopify.com/s/files/1/1487/1618/files/20250903_EBBETSHATS3593_aab1ce3a-9670-482c-b50d-aedde93f2129.jpg?v=1757703247","https://cdn.shopify.com/s/files/1/1487/1618/files/20250903_EBBETS_HATS3595.jpg?v=1757703247","https://cdn.shopify.com/s/files/1/1487/1618/files/20250903_EBBETS_HATS3596.jpg?v=1757703247","https://cdn.shopify.com/s/files/1/1487/1618/files/20250903_EBBETSHATS3597.jpg?v=1757703247","https://cdn.shopify.com/s/files/1/1487/1618/files/Brim-detail-updated_1_8f0a8d78-7956-4787-8cb8-b9784bb20d3e.jpg?v=1775851444"],"price":41,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:30:38.646Z"},"share_url":"https://firestarter.network/l/lst_XW3HDNAV","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
