His coach said that he was \"a most adept pass catcher…but his lack of weight was a drawback.” He graduated in 1940, wearing a shawl cardigan sweater just like this one. \nThe 1940 Shawl Collar Sweater pays tribute to life at Harvard in the 1930s and 40s, made with a heavyweight alpaca/wool blend and adorned with felt letters and vintage-style buttons. \n ","images":["https://cdn.shopify.com/s/files/1/1487/1618/files/HarvardUniversity1940ShawlCollarSweater1.jpg?v=1755174375","https://cdn.shopify.com/s/files/1/1487/1618/files/87896_MYO_013_04-2.jpg?v=1755098257","https://cdn.shopify.com/s/files/1/1487/1618/files/HarvardUniversity1940ShawlCollarSweater1_60ce9a0d-3b6a-49a8-b518-b3fbe187750f.jpg?v=1755098257","https://cdn.shopify.com/s/files/1/1487/1618/files/HarvardUniversity1940ShawlCollarSweater2_08dcdb35-9438-4685-895e-8003033de540.jpg?v=1755098257","https://cdn.shopify.com/s/files/1/1487/1618/files/HarvardUniversity1940ShawlCollarSweater3.jpg?v=1755098257"],"price":224,"currency":"USD","in_stock":true,"inventory_qty":39996,"dynamic_pricing":false,"listed_at":"2026-06-18T20:30:39.902Z"},"share_url":"https://firestarter.network/l/lst_YDbQCTSI","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
