Gray canvas tote bag with pink cat pin

I lost my gray canvas tote bag yesterday around 3pm outside Powell's City of Books on West Burnside. It's a medium-sized bag with a brass zipper that sticks a bit and a pink enamel cat pin on the strap. Inside there's a faded photo of my grandmother and a blue sticky note in the inner pocket that reads 'Mom's list'. This bag means a lot to me—I really need it back.
