Framed abstract painting with gold frame

I lost my framed abstract painting yesterday afternoon near the NH State House on North Main Street in Concord. It's a 24x18 inch canvas with cool blues and silvery wisps, set in a slightly scuffed gold frame. The back has a small coffee ring stain and the bottom-right corner bears a barely legible signature, 'K. Whitman 2018.' It was a gift from my late aunt and carries a lot of sentimental value, so I’m really hoping it turns up. If you’ve seen anything matching this, please reply here or contact me—I’d be forever grateful to get it back.
