Framed abstract painting with white frame

I lost my small framed abstract painting yesterday around 3pm near the Michigan Theater on State Street in Ann Arbor. It's an 8x10 canvas oil with cobalt blue and teal swirls and a bright orange accent, housed in a clean white frame that shows a tiny scratch along the bottom edge. On the back there's a faint handwritten note—'Studio 11, A2'—and my initials A.R. It's sentimental to me; it was a gift from my sister who moved away, and I really hope to get it back. If you found it, I’d be grateful to hear from you.
