Black RFID passport wallet with initials SK

I found a black RFID passport wallet this evening around 6:45 pm near Market Square, downtown Pittsburgh, just outside the PPG Place entrance. It's a slim leather wallet, roughly the size of a paperback passport holder, with a matte finish and a tiny brass zipper pull. Inside, there are a few cards and a faded boarding-pass stub, and the inside pocket is stamped with the initials 'SK' in silver ink. The burgundy lining still adds a splash of color and the whole thing looks a little worn but usable. If this belongs to you, I’m happy to drop it off at the Market Square information desk or we can arrange a quick meetup downtown to return it.
