Black Yamaha snare drum found in Portsmouth

I found a black Yamaha snare drum, 14x5.5 inches, with chrome hardware. It's in pretty good condition, just a few light scratches on the shell. I found it this afternoon around 1:30pm in Market Square, near the Portsmouth Music Hall on State Street in Portsmouth, NH. There's a white sticker on the inner rim with the initials 'A.M.' and a pair of Vic Firth sticks tucked inside the shell. If this belongs to you, I’d really like to get it back to its owner—please reach out with a description of the case or the sticker.
