Framed abstract painting, blue and gold

I lost a framed abstract painting yesterday around 3pm in the Mohegan Sun Arena parking lot in Uncasville. It’s an 18x24 inch canvas, mostly cobalt blue with shimmering gold accents, housed in a distressed oak frame that has a small scuff on the bottom edge. On the back there’s a pencil note that says 'For Mother's Day' and a faint fingerprint near the lower-right signature. It has serious sentimental value to me—it's a gift from my grandmother that I’ve kept in the living room for years. If anyone found it, I’d really appreciate getting it back.
