Small framed abstract canvas in gold frame

I lost my small framed abstract canvas with a brushed gold frame yesterday around 3pm near the Starbucks on High Street in Winchester, Hampshire. It's an 8x10 inch piece with teal and copper swirls on a cream background, and the frame has a tiny nick along the bottom edge. There's a barely visible pencil signature 'P. Patel' in the bottom-right corner, plus a faint coffee ring on the back and a small sticker with my name. This piece really means a lot to me—it was a gift from my grandmother and has sentimental value, so I’d really appreciate getting it back if anyone finds it.
