Brooklinen white duvet cover with navy piping

I lost my Brooklinen white duvet cover with navy piping yesterday around 3pm near the City Dock on Dock Street in Annapolis. It's a king-size duvet cover, bright and crisp, in good condition aside from a small coffee stain near the bottom corner. The inside label reads 'Brooklinen King' and there’s my initials 'P.P.' embroidered in the corner. It was a gift from my grandmother and has sentimental value, so I’d really appreciate it being returned if anyone found it around the City Dock area or along Main Street between Dock Street and West Street.
