Inside the box, sandwiched between bubble wrap, each record comes in a unique semi-transparent sleeve with gritty patterns overlaying the translucent outer sleeve - an inner sleeve further protects the records. The album comes with a download card (because the Highway Hi-Fi wasn't designed for 180gm 12" platters), and the inside-bottom of the box has track names.
Aside from the titles on the side of the box, there didn't appear to be any credits. The official unboxing video posted earlier mentioned something about "being contaminated" and, honestly, I didn't see any evidence of that at first.
But I kept looking.
