{"type":"firestarter.listing","listing":{"id":"lst_GPeww0y4","product_name":"San Francisco Seals (PCL) Long Sleeve Graphic Tee","category":null,"description":"GRAPHIC TEE HONORING THE SAN FRANCISCO SEALS\nHistory: The San Francisco Seals joined the Pacific Coast League in 1903, and from that time until their departure in 1957 they were one of the league's most colorful franchises. The 1931 season saw the opening of the magnificent Seals Stadium, where the club remained until the end. Joe Dimaggio began his career with the Seals and had a 61-game hitting streak in 1933. However, the most beloved Seal was Lefty O'Doul, who, after starting his minor league career with the club, came back after he retired as a player to manage his old team.\nMade with medium-weight 200gsm cotton, this tee is designed to be worn over and over again. The shirt is finished with a subtle embroidered “Ebbets” logo on the left chest and a printed graphic on the back and right sleeve honoring the San Francisco Seals.","images":["https://cdn.shopify.com/s/files/1/1487/1618/files/20250917_EBBETS4518.jpg?v=1759175164","https://cdn.shopify.com/s/files/1/1487/1618/files/20250917_EBBETS4523.jpg?v=1759175173","https://cdn.shopify.com/s/files/1/1487/1618/files/20250917_EBBETS4519.jpg?v=1759175203","https://cdn.shopify.com/s/files/1/1487/1618/files/20250917_EBBETS4520.jpg?v=1759175216","https://cdn.shopify.com/s/files/1/1487/1618/files/20250917_EBBETS4521.jpg?v=1759175220"],"price":29,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:30:38.584Z"},"share_url":"https://firestarter.network/l/lst_GPeww0y4","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
