Blue USB drive with initials 'AS' found downtown

Found a small USB drive this afternoon around 3:15pm outside the Busch Stadium entrance along 8th Street in downtown St. Louis. It's a silver USB drive with a blue label on the front and a tiny dent on the corner; the label has the initials 'AS' in white. I haven’t opened it and don’t know what's inside, but it looks like it might hold personal photos. If you recognize it, message me with the initials on the label and the approximate capacity (64GB or 128GB) and I’ll return it right away.
