Framed desert-toned acrylic painting, 18x24 inches, missing

I lost my framed desert-toned acrylic painting yesterday around 3:15 pm. It's an original 18x24 inch piece, in a white wooden frame with a slim gold inner edge. The canvas features warm desert tones—terracotta skies and sage dunes—with a tiny sun motif in the lower left corner and my signature, 'L. Ortega', in the lower right. The back has a small sticker from a local market and a faint coffee ring along the bottom edge. It means a lot to me; it was a gift from my sister after a Phoenix trip. I’m really hoping someone found it and can return it—please reach out if you saw a painting matching this near Central Ave by the Phoenix Art Museum.
