At some point during the first 2 weeks of the engagement in Vegas, Elvis presented Muhammad Ali with a robe emblazoned "The People's Champion". Ali's fond recollection of Elvis was that, "I felt sorry for him because he didn't enjoy life the way he should. He stayed indoors all the time. I told him he should go out and see people."
At some point Ali presented his boxing gloves to Elvis with the inscription "You're the greatest" on the left glove and "To Elvis, my main man, form Muhammad Ali" on the right.
