Here's an Amazing Race envelope (torn) from season 18 "Unfinished Business" which saw 11 teams return to play again. Envelopes are given out at the start of each leg as well at tasks locations and at the completion of tasks and usually contain a slip of paper that tells the player what they have to do next.
I'm always on the hunt for Survivor or Amazing Race items, feel free to leave a comment or check out my other items :)
