Framed acrylic landscape painting in gold frame

I lost my framed acrylic landscape painting yesterday around 3pm. It’s an 18x24 inch piece in a light brown wood frame with a thin gold border. The scene shows a sunset over rolling hills and a small red barn, done with bold brushstrokes in warm oranges and greens. It’s signed 'M. Hart 2017' in the lower right corner, and the back still has a Cedar Arts Gallery label with the hanging wire. I think I left it on a bench near the courthouse square in downtown New Philadelphia after a quick coffee run. It has sentimental value—my late aunt gave it to me. There’s a tiny purple smudge along the lower left edge and a small scratch on the bottom-right corner of the frame.
