Blue travel mug found near Spokane Public Library

I found this blue stainless steel travel mug yesterday around 3pm outside the Spokane Public Library on Main Avenue. It's about 9 ounces, with a black silicone grip and a white sticker of a mountain silhouette peeling a bit at the corner. The lid closes snugly but the seal shows a little wear, and there's a faint coffee smell that clings to the metal. On the bottom, someone etched the initials 'A.R.'—a hint for the owner to spot it. It looks well-used but in decent condition, and I’d love to return it to its rightful owner as soon as possible.
