JBJ Wedding memorabelia question

Hi all-- First time on.
My sister-in-law got a leather "high school letterman" style jacket and t-shirt from a fund raising event/silent auction. She found out what a fan I am and sent it to me.
The jacket and t-shirt say Elvis Tour '89
the t-shirt has a bunch of made-up/fake/funny "tour dates" on the back and Elvis Tour '89 on the front.
On the back of the shirt "April 29 Graceland Chapel" is hand-written in.
Now I don't know who did that but I'm assuming this "gear" has something to do with Jon and Dot's wedding.
Can anyone confirm?
Thanks

I don't think it has something to do with the wedding. When you watch I think it was the AAA-video you can see that at the curton that separates Jon's room behind the stage also stands something with Elvis. He probably was on an Elvis-trip at that time LOL.
