An uncommon object. What is it?

Challenge #14 in the Voter awareness.... series. Hosted by barb_s.
Challenge has finished
Have you ever been invited to a party where you brought something uncommon that guests examine and guess what it is? Show that kind of object, the whole object, not a closeup macro. Plan your photo as if you were creating a still life. Lighting and composition are important. This challenge is not a snapshot guessing game. It's about a well executed photograph.
