US passport found near Las Olas Riverfront

I found a US passport this afternoon around 3:45pm near the Riverwalk at Las Olas Boulevard in Fort Lauderdale. The burgundy cover is a touch creased with the Great Seal still clear, and there's a small coffee ring along the back edge. Inside, the standard data page is visible, and the photo shows a traveler in a light blue shirt—nothing legible from the outside, of course. I slipped it into a protective pouch in my bag to keep it safe and I really hope to reunite it with its owner.
