Ivory king-size duvet cover with navy piping

Found this ivory king-size duvet cover set this afternoon around 1:45pm near the entrance to the Original Farmers Market on 3rd Street and Fairfax in Los Angeles. It's soft Egyptian cotton with navy piping along the edges and a small monogram 'JS' stitched in the top-left corner. The set includes the duvet cover and two matching shams, clean and lightly wrinkled from being carried, with a tiny coffee stain on the inner corner of the duvet cover that could help identify it. I know bedding can mean a lot to someone, so I’d love to reunite it with its owner if this is yours.
