Black tuxedo jacket with satin lapels

I found a black tuxedo jacket this afternoon around 2:15 pm in the parking lot behind Market Street Plaza in New Philadelphia, Tuscarawas Co. It's a men's size Large, wool-blend with satin lapels and a couple of light wrinkles from being tossed into a bag. Inside the left lining there's a tailor's tag that reads 'M Rivera,' and I tucked a folded emerald-green pocket square back into the inner pocket for safekeeping. There's a tiny wear mark on the left elbow and a missing button on the cuff, but otherwise it's in decent shape. This seems like it came from a formal event—I'd really like to get it back to its owner. If this sounds like yours, tell me the tag name and what color the pocket square was.
