Framed watercolor painting, dusk landscape, 8x10 in

I lost my framed watercolor painting yesterday around 3pm near the Peace Gardens outside the Millennium Gallery on Castlegate in Sheffield. It's a small 8x10 inch piece, blues with gold accents, in a black wooden frame with a tiny chip on the bottom-right corner. On the back there's a purple circular sticker with the artist's initials 'LP' and a faint pencil inscription that reads 'Dusk Meadow'. It was a gift from my late grandmother and really sentimental to me, so I would be heartbroken if it doesn't turn up. If anyone found it, drop me a line and I can share a photo to verify.
