I had one back in the '70s that had the Challenger logo on a round disc that was attached to a leather backing like this one, but the logo ran 90 degrees from the way this one does. Also, mine didn't have the R/T on it. For many years now, even while driving Thunderbirds and a Mustang, I've always used a metal keychain fob that has the old Chrysler Corp. insignia on it.
