Framed floral watercolor with gold frame

Found this framed watercolor this morning around 7:15am outside the Roanoke City Market Building on Market Street. It shows a bright spring bouquet in a white ceramic vase against a pale blue background. The piece is about 11x14 inches, in a gold filigree frame with a small crack along the bottom edge of the glass, and the back is taped shut. There's a signature in the lower-right corner that reads 'M. Rivera.' If this sounds like yours, I can hand it over to you at the Market Street entrance.
