No "Deluxe Edition" sticker because they were poor quality and were coming off.
He said only one version of the LP -- when I said mine wasn't gatefold, he said it "has to be" -- I pointed him toward this forum, and said that while I didn't open mine, it looked to be not gatefold from the side and from the comments here.
