Framed abstract painting with cobalt blues.

I lost my framed abstract painting yesterday around 3pm, somewhere near Michigan Ave and the Riverfront in South Bend, MI. It's a 12x16 inch black wood frame with a white mat, showing cobalt blues and sunlit gold swirls—very loose, watery strokes that catch the light. The back has a small gallery sticker with the artist's initials 'L.K.' and a faint pencil number; the frame has a tiny dent along the bottom left corner and a chipped gold edge that makes it stand out. It was a gift from my aunt and holds real sentimental value, so I’m really hoping it turns up. If you’ve seen it or picked it up accidentally, please reach out and I’ll explain more.
