{"type":"firestarter.listing","listing":{"id":"lst_rHLFZ7tQ","product_name":"Harvard University Cotton Twill Baseball Jersey","category":"Jerseys_CT","description":"  A BREATHABLE COTTON TWILL JERSEY HONORING THE 1967 HARVARD UNIFORMHistory: Pitcher Ray Peters struck out 224 batters over the 1967 &amp; 1968 seasons, and he still holds the record at Harvard for most single-season Ks. Even though Peters only had a \"cup of coffee\" in the bigs, playing two games for the Milwaukee Brewers in 1970, his legacy will live on as the pitcher who led the Crimson to their first appearance in the College World Series.\nInspired by Harvard’s home uniform from 1967, this jersey is made with lightweight, durable cotton twill and stays true to the designs of the era, with period-correct lettering and logos.","images":["https://cdn.shopify.com/s/files/1/1487/1618/files/20250804_EBBETSFIELD2595.jpg?v=1754502957","https://cdn.shopify.com/s/files/1/1487/1618/files/20250804_EBBETSFIELD2600.jpg?v=1754502960","https://cdn.shopify.com/s/files/1/1487/1618/files/87896_MYO_013_04-2_02d64f64-5794-4867-8618-caddcf138b76.jpg?v=1755098308","https://cdn.shopify.com/s/files/1/1487/1618/files/20250804_EBBETSFIELD2596.jpg?v=1755098308","https://cdn.shopify.com/s/files/1/1487/1618/files/20250804_EBBETSFIELD2599.jpg?v=1755098308","https://cdn.shopify.com/s/files/1/1487/1618/files/20250804_EBBETSFIELD2598.jpg?v=1755098308","https://cdn.shopify.com/s/files/1/1487/1618/files/20250804_EBBETSFIELD2601.jpg?v=1755098308"],"price":112,"currency":"USD","in_stock":true,"inventory_qty":29997,"dynamic_pricing":false,"listed_at":"2026-06-18T20:30:38.889Z"},"share_url":"https://firestarter.network/l/lst_rHLFZ7tQ","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
