This is a previously-owned, youth-large (YL / size 14-16), purple sweatshirt with “Grand Traverse Lighthouse Museum / Northport, Michigan” printed on the front. It measures approximately 18 inches (from underarm seam to underarm seam) and is in good condition (Jerzees brand, 50% cotton / 50% polyester). Grand Traverse Light is a lighthouse in the US state of Michigan, located at the tip of the Leelanau Peninsula, which separates Lake Michigan and Grand Traverse Bay. It marks the Manitou passage, where Lake Michigan elides into Grand Traverse Bay. In 1858, the present light was built, replacing a separate round tower built in 1852.
