Hi Bob - The Hearns Hagler key is a real room key. I believe it was issued in a commemorative sense, along the lines of the Evel Knievel jump over the fountains hologram key that also obviously wasn't issued at the time of his jump, but in honor of a memorable event at Caesars. The 1966-2006 Caesars hologram key has old and new pictures of Caesars depending upon how you hold the key.
