Inspired by a trip to the circus, Gilroy first drew a seal balancing a pint glass on its nose with a zookeeper running after it shouting, \"My Goodness, My Guinness!\" After that came a whole menagerie of animals — including an ostrich, a tortoise, and (most iconic of all) a toucan — all laden with beer, rendered in Gilroy's colorful, whimsical style. The designs caught on big time, meaning this eclectic group of animals can claim at least some responsibility for the fame of the world's most popular stout.\nMade with medium-weight 200gsm cotton, this Guinness x Ebbets Field graphic tee features a screen print of the Guinness harp on the chest and the pint-toting tortoise on the back under the famous tagline, \"Lovely day for a Guinness.\"","images":["https://cdn.shopify.com/s/files/1/1487/1618/files/20260216_EBBETS8424.jpg?v=1772482936","https://cdn.shopify.com/s/files/1/1487/1618/files/20260216_EBBETS8422.jpg?v=1772482936","https://cdn.shopify.com/s/files/1/1487/1618/files/20260216_EBBETS8423.jpg?v=1772482936","https://cdn.shopify.com/s/files/1/1487/1618/files/20260216_EBBETS8425.jpg?v=1772135433"],"price":46,"currency":"USD","in_stock":true,"inventory_qty":59994,"dynamic_pricing":false,"listed_at":"2026-06-18T20:30:38.129Z"},"share_url":"https://firestarter.network/l/lst_4MxeuHPP","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
