Grey canvas tote bag with red interior

I lost my grey canvas tote bag yesterday around 3pm near the Forum in Norwich. It's a medium-sized bag with black cotton handles and a bright red lining, plus a small scuffed metal zipper pull and a blue fabric loop on the inner pocket. Inside there's a folded photo of my dog and a tiny brass keyring marked 'L&C'—two details that could prove it's mine. The tote was a gift from my sister and has serious sentimental value; I hate the thought of it being out there, and I’d really appreciate it being handed back if found.
