Silver Rococo Napkin Ring

Silver Rococo Napkin Ring is a treasure found in Uncharted 3: Drake's Deception. It is found in the level Sink or Swim.

As you are climbing up a hallway, when you grab onto a white door it will swing open. Climb into the room, and then climb into the room above it via the door on the ceiling. In that room, straight ahead of you, is a bathroom. Inside that bathroom is the treasure.
