I bought mine from the same seller, I believe. From France? She met Jeff a few times. When I bought mine she said she didn't want to sell her autographed magazines. Looks like she let one go. She's a lovely girl and honest seller. I used to have an original signed Grace CD from someone that worked in promotions for (then) Columbia. It had hearts on it and his signature. I resold it for $450 AU. Now it's worth over 2,000. I'll attach my autograph and a used guitar pick ☺
Oh and yes, it's no doubt authentic. Jeff liked to draw hearts, and he drew them just like that. I like the dedication, too. Must have been after a concert. He toured extensively in Europe.
