Dark blue US passport in black leather sleeve

Lost my dark blue US passport yesterday around 4pm near the Iowa City Public Library on College Street, just by the pedestrian bridge leading to the Old Capitol. It was tucked inside a black leather travel sleeve with a small red maple leaf sticker on the front. The passport itself is a standard US book, a little worn from travel, with a faint coffee stain along the back cover and a tiny scratch on the top edge. This passport is important to me—it's tied to a family trip and I really need it back for an overseas appointment next month. If you found it, email me at [email protected]; I’d be incredibly grateful to get it back.
