Framed abstract art print, blue and gold

Lost my framed abstract art print yesterday around 3pm near the Ashtabula Harbor Market on Main Street. It's a 24x30 inch print of an abstract seascape in blue and gold, housed in a black wood frame with a tiny gold accent. The frame has a small crack along the bottom edge and there's a pencil signature in the lower margin—initials A.R. This was a gift from my grandmother and holds a lot of sentimental value; I really need it back.
