Gray queen duvet cover with navy piping

I lost my gray queen-size duvet cover with navy piping yesterday around 3pm near the Chautauqua Public Library on Main Street. It's from the CozyNest line, soft cotton with a hidden zipper. Inside the corner seam there are small navy initials 'PK' embroidered, and there's a tiny coffee stain on the inner edge. It has sentimental value; it was a gift from my grandmother, and I really need it back. If anyone found it, I’d appreciate getting it back and we can arrange a quick meetup around the library or at the town gazebo in Chautauqua.
