Found queen-size gray duvet cover with navy piping

I found a queen-size duvet cover set this afternoon around 3:15pm near the Brickell City Centre entrance on S. Miami Ave. It's a storm gray cotton percale with a subtle geometric pattern and navy piping along the edges. The zipper closure works smoothly, and there's a small embroidered monogram 'MR' on the inner corner tag—nice little detail that might help identify the owner. The fabric feels premium, lightly used but clean, no stains. I know how sentimental bedding can be—if this is yours, please reach out so I can return it to you.
