Framed abstract art canvas in black frame

I lost my framed abstract art canvas yesterday around 3pm near the Old Market in downtown Omaha. It's a 24x30 inch canvas, mostly teal and charcoal with a slim gold metal frame, and there is a tiny coffee stain along the bottom edge. On the back there is a small sticker with the code LM-47. This piece was a gift from my grandmother and holds sentimental value, so I'm really hoping it turns up. If you found something matching this, especially around 13th Street, Howard Street, or the parking lot behind the Blackstone District, please reach out. I would be so grateful to have it back.
