Black leather tote with lobster charm

I lost my black leather tote yesterday around 3pm. It’s a medium-sized Rebecca Minkoff tote with a tan interior and a tiny brass lobster charm hanging from the zipper pull. Inside, the pink satin lining is slightly worn and there’s a fabric label stitched with the initials 'KB'. I was in the Old Port area of Portland, Maine, near the Starbucks on Exchange Street when I think I last had it, after grabbing coffee and heading toward the marina. It means a lot to me—it's a gift from my sister and it holds a few family photos—really hoping someone found it and can return it.
