Lost watercolor painting of a vibrant sunset over the lake in a simple wooden frame, left at Riverfront Park in Shreveport.

I lost a lovely watercolor painting that captures a vibrant sunset over the lake, while visiting Riverfront Park in Shreveport. It has a simple wooden frame, and it painted by my late grandmother. I accidentally left it propped against a tree while I took some photos, and when I came back, it was gone. It holds a lot of sentimental value, and I would love to get it back.
