What is a good symbol for Jack in "Lord of the Flies"?

We're reading "Lord of the Flies" in my English cl and we have to do a character profile on Ralph, Jack, or Piggy. We have to draw something to symbolize the character, like a conch or a pig. I'm choosing Jack, and I want to do something other than a spear or choir robe, which is what everyone else is doing. What can I make that's original but relevant?
