Glass-top coffee table with brass frame

I lost my glass-top coffee table with brass frame yesterday around 3pm near the Nelson-Atkins Museum's Oak Street entrance in Kansas City. It's a mid-century style piece, about 40 inches long, with a clear tempered glass top that has a beveled edge and a brass frame that shows a little patina but is sturdy. There's a small scratch along the top edge and a faint KC initials etched near the bottom of one leg, which makes it easy to spot. It really matters to me—it's the centerpiece of our living room and was a gift from my grandmother, so I’d be grateful to get it back.
