{"product_id":"sisyphus-happy-black-t-shirt","title":"Sisyphus Happy Black T-shirt","description":"A soft, lightweight tee that turns math and myth into a playful statement. The design shows Sisyphus pushing his boulder along a sine wave — a clever nod to alternating current and cyclical effort — while the bold “SISYPHUS HAPPY” caption adds wry humor. It feels laid-back on the skin and looks intentionally casual on the couch, at a lecture, or during late-night study sessions. Wear it when you want to smile at the struggle, start a conversation about science or philosophy, or keep your style simple but smart.\u003cbr\u003e\u003cbr\u003eProduct features\u003cbr\u003e- 100% ring-spun cotton for a soft, lightweight feel (varies by color\/blend)\u003cbr\u003e- Tubular, side-seam free construction for a smooth, waste-reducing fit\u003cbr\u003e- Ribbed, elastic crew neckline with shoulder tape to maintain shape\u003cbr\u003e- DTG prints on body with optional DTF sleeve and neck label prints\u003cbr\u003e- OEKO-TEX® STANDARD 100 certified and ethically sourced cotton\u003cbr\u003e\u003cbr\u003eCare instructions\u003cbr\u003e- Do not dryclean\u003cbr\u003e- Do not bleach\u003cbr\u003e- Tumble dry: low heat\u003cbr\u003e- Iron, steam or dry: low heat\u003cbr\u003e- Machine wash: cold (max 30C or 90F), with similar colors \u003cbr\u003e","brand":"Printify","offers":[{"title":"S \/ Black","offer_id":57431305224572,"sku":"19676105440840040868","price":29.99,"currency_code":"USD","in_stock":true},{"title":"M \/ Black","offer_id":57431305257340,"sku":"21477698320550783517","price":29.99,"currency_code":"USD","in_stock":true},{"title":"L \/ Black","offer_id":57431305290108,"sku":"32142236126141311540","price":29.99,"currency_code":"USD","in_stock":true},{"title":"XL \/ Black","offer_id":57431305322876,"sku":"16179456997792690299","price":29.99,"currency_code":"USD","in_stock":true},{"title":"2XL \/ Black","offer_id":57431305355644,"sku":"26658444571072190964","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0951\/9280\/9852\/files\/20260910193935-1f1ad4f5-a7ff-65c2-aab2-bacf62f0e0b3.jpg?v=1789069358","url":"https:\/\/www.welcomeartist.com\/products\/sisyphus-happy-black-t-shirt","provider":"WelcomeArtist","version":"1.0","type":"link"}
