Found silver pocket metronome with red button

I found a silver Wittner pocket metronome with a bright red start/stop button this afternoon around 4:15 pm, sitting on the curb by the Michigan Theater on Liberty Street in downtown Ann Arbor. It's palm-sized, with a brushed metal finish and a small black carrying pouch that looks worn from gig bags. On the back there’s a tiny sticker of a cartoon drummer, which should help you spot it if you left a clue or two. The battery cover is a bit loose, and it ticks reliably when you test it, so it seems like someone was using it recently. If this is yours, tell me a detail about the drummer sticker or the pouch contents and we can meet up near the theater to swap.
