Yeh, I think there was a copyright problem with the Eden artwork... maybe not copyright but something like that, and subsequent reissues had to use a different cover. Must've got sorted coz the extra disc version and Return To Eden both used the original art.
What I liked about the JD/NO artwork (and this was noted in a JD/NO documentary), you could go into HMV, look at the new releases on the wall behind the counter and know instantly, even without identifying text, which one 'New Order' was! Distinctive...
