Perhaps this is what happened.
What if a fan owns a picture of Mary Ann Mobley and Elvis.
Okay the fan owns the picture not EPE and she wants Mary Ann Mobley to autograph it.
she's not trying to sell it she just would like Mary Ann to autograph it but EPE officials say no.
Would EPE be entitled to 33% if that were the case.
Now if EPE were actually selling pictures of Elvis at the event for fans to buy then they'd be entitled to profit from that.
Maybe that's what Mary Ann was talking about when she said she didn't want the fans to buy any photos from EPE for her to sign.
Because maybe Mary Ann Mobley doesn't really like the people at EPE and doesn't want them to profit from her.
Assuming Viva Elvis' quote is accurate.
