MUHAMMAD ALI ONE-OF-A-KIND AUTOGRAPH

Description

MUHAMMAD ALI ONE-OF-A-KIND AUTOGRAPH.
Muhammad signed this for me personally when he appeared on an episode of "Diff'rent Strokes" in 1979.
BACKGROUND
Before any kind of home video was available to the general public, I owned a professional Sony 3/4" deck. The cassettes were the size of a medium book. When Ali won his third and final championship versus Leon Spinks, I recorded it at home; it was on "traditional" network TV at the time.
Working at Norman Lear's Tandem Productions/TAT Communications, I had access to many celebrities. When I learned that Ali was going to be on "Diff'rent Strokes," I brought in my video of that fight and he signed the card which fits on the outside of the black plastic case.
I've never needed to have his signature authenticated because I was there.  There's a reason I have a 100% ebay rating.
