Navy Herschel backpack with orange zippers

Lost my navy blue Herschel Little America backpack yesterday around 4pm, outside the Bath Spa train station on Manvers Street. It's a 24L backpack with a light gray interior, and the laptop sleeve fits a 13-inch MacBook Pro. There's a bright orange zipper pull on every compartment, and a small green fox-shaped keychain I clipped to the front pocket. I also noticed a faint coffee stain on the bottom corner. It holds work notes and a photo of my grandmother, so it really means a lot to me—if anyone found it, please get in touch; I’d be so grateful to have it back.
