Framed landscape painting, black frame

I found a framed landscape painting this afternoon around 2:15pm near the Lansing City Market on East Kalamazoo Street. It’s a 16x20 inch oil painting in a glossy black wooden frame with a tiny chip along the bottom edge. The scene shows green hills, a blue sky, and a small red-roofed cottage tucked in a corner. On the back there’s a handwritten tag with the initials 'M.R.' and a faint coffee ring, which are 1-2 clues to identify it. If you think it’s yours, email me at [email protected] and we’ll figure out next steps at the City Market lost-and-found desk.
