Lost hand-painted ceramic bowl with vibrant blue and yellow floral designs near the Lincoln Memorial, National Mall, Washington DC.

I lost a stunning hand-painted ceramic bowl while visiting the National Mall last week. It has vibrant blue and yellow floral designs on it and is approximately 12 inches in diameter. I believe I might have accidentally left it on a bench near the Lincoln Memorial while taking some pictures. It held sentimental value, as it was a gift from my grandmother, and I'd really love to get it back if anyone finds it.
