All discs pictured have track 5 listed as "Heartbreakers" whereas all the inserts have the tracklisting with the correct Heartbreaker with no "S" on the end
Added booklet scans as well as the back which is a slight variation to the one already uploaded (no WE835 number in the bottom right corner).
I bought this in December 1987 to replace a well worn vinyl copy I'd been given two years earlier, the quiet bit towards the end of "Thank You" was completely buried under surface noise, to the point where I thought it had been faded out completely, so it was nice to hear it properly for the first time on CD.
Anyway this was the original CD version, mastered by Barry Diament in the Atlantic studios, the "original 1987 Compact Disc mastering" according to Wikipedia. Although it was probably not mastered but released in that year, it seems to be confirmed that neither this nor any other Led Zeppelin album was released on CD before 1987.
I corrected this issue from Atlantic UK to Atlantic International, as it was pressed and printed in Germany and also includes the US catalogue number. The European (or rather non-US) cat# (240 037) was a separate number not related to the barcode, and thus it was definitely released earlier than the one with main cat# 7567-81526-2. I'm still not sure about the release date but as I have seen no database claiming the first CD issue of Led Zeppelin II came out before Jan 1987, I gave it this date (moving the one with cat# 7567-81526-2 to 1988 though that one was probably later).
