Cream quilted duvet cover with navy piping

I’m missing my cream quilted duvet cover with navy piping, queen size. It’s soft cotton, and there’s a tiny coffee stain on the inside hem plus a blue embroidered monogram 'AF' on the top-left corner. I last saw it yesterday around 3pm near the Lancaster Central Market on Market Street, outside the coffee shop. It was a gift from my grandmother and has serious sentimental value; I really need it back. If you found it, email me at [email protected]—I’d be forever grateful to get it back.
