Framed watercolor landscape with blue-green border

I’m hoping someone picked it up by mistake. I was at a small coffee shop on Stanton Street in downtown El Paso yesterday around 3pm when I last saw it resting on the chair. It’s an 11x14 inch canvas of a desert sunset, housed in a blue-green frame that’s chipped along the bottom edge. The painting is signed 'A. Flores' in the lower-right corner—there’s also a faint coffee stain on the back. It means a lot to me; it was a gift from my aunt and I’d really appreciate getting it back.
