That was one heck of a story. You made your aunt seem like a creeper/stalker though.

And she sat down on the blacktop and listened to the conversations he had

Maybe I am interpreting aunt June in the wrong way! She definitely seems sweet - especially holding that birthday gift as a surprise for a while! As for its authenticity - there is much more value to the personal story behind it than the value of an autograph. When your aunt has one party with a celebrity/star-athlete and she thinks of you - that is golden!

P.S. Love the pun in his autograph: "Best Swishes". Makes it extra worth!
